This is another plumbing tray calculations video. <\/p>

And this video will be discussing the 45 degree parallel offset. In our picture we have here, happens to be a three pipe parallel offset, 45 offset, three offset. Any parallel can be anything from two pipes onwards. <\/p>

In this case we have three pipes for our example. In the parallel offset, our key goal is to maintain the spread between all the horizontal piping. So the distance between A to center of D, we want to maintain it all through the offset. <\/p>

including where the travel pieces are. So between pipe B and E, we want to maintain that same spread, whatever number that is, whatever measurement it is, we'll maintain it. And then when we go back horizontal again, continue that same measurement between pipe C and E. So let's say as example, between the center of center measure between A and D was 12 inches. We would want to name 12 inches between B and E and 12 inches between C and L. <\/p>

Same on the bottom. The bottom doesn't have to be the same spread or the same distance between the two pipes. So between pipe D and G, it could be a spread of six inches, let's say, center-center. We wanna maintain that all the way through to two travel pieces between E and H. We wanna maintain that same six inches. And then after that as well, we go horizontal again between F and I. <\/p>

We wanna maintain that same six inches. So again, all through the offset. key factor in maintaining this throughout will be what is known as our spread allowance. In order to get our spread allowance we need to know what our spread is and again that is just the center to center dimension between the two horizontal pipes. <\/p>

So between A and D which happens to be what J is and the other spread down the bottom between D and G which happens to be whatever H is. getting started is we need to know our offset factors. We can get that from our offset factor table. And since we're looking at the 45 degree, we can go right to the bottom of the page here where it says for parallel offsets. <\/p>

In order to find what's called the spread allowance, which we'll talk about in a second, we need to know the spread and then multiply it by the factor. And the being for 45 degree offsets, 0.414. So looking at this diagram on the screen here, we have a three pipe parallel offset again. And what we're trying to do by using the spread to calculate the spread allowance is to help us either lengthen or shorten the pieces of pipe we need in order to main that spread all throughout the offset. So what I mean is between pipe B and D, We'll notice that we draw a center line from the center of the 45 off of A all the way down to D. <\/p>

D is much longer than A. It goes from that red line, that center line from the 45 over to its 45 center line. And that distance in between there is our spread allowance. And again, in order to calculate that spread allowance, we need to know the spread between A and D, which is our J measurement over here. <\/p>

And we'll be timesing that by 0.414. When you're going through the offset on the upper level, we also run into that spread allowance thing again. The same exact spread allowance as previously mentioned, but now it's between F and C, or C and F. We take a center line from the 45 of F all the way up to C. And we get the spread of the two lines. And we can see that the spread of the two lines is now 0.414. <\/p>

notice that C is a little bit longer and C is this much longer over to the next red line which is the center line of its 45. And again so that distance in between the two red lines is its spread allowance that we need to know. And for us we're going to call it spread allowance one. <\/p>

So we need to know the spread. In our case the first spread which which equals the center center dimension of J. Spread allowance equals spread x. Spread allowance 1, which we're working on right now at the top. Our spread is j, and we times it by the factor. So our spread allowance formula afterwards will be spread allowance equals spread times 0.414. <\/p>

and our spread representing our J. Once we calculate this, we'll have to do a spread allowance for the bottom partly offset, because the spread between the two pipes at the bottom end could be a lot different, smaller or larger. So we need to know what the spread is between D and G so we can maintain it all the way through the piping offset, which was also referenced by the measurement K. So first we need to know the spread. Spread 2, we're going to call it, Spread Allowance 2, the Spread 2 is known as this k dimension from center to center. A little bit of error on the formula here, but our Spread Allowance is going to equal Spread X. <\/p>

And in brackets, it should say SA2, because we're working on SA2, as in the picture. That's our spread allowance 2 we're working on. And we're going to take our spread K and times it by the factor. <\/p>

So again, to find spread allowance, and it should say SA2 equals spread times 0.414, which is K for spread. Once we have the spread allowance, now we can work on finding all the different pipes. So finding A, D, G, B, E, H, C, F, and I. So looking at pipe A, center-center, if we want to find that, we have to find a pipe that's parallel to it, adjacent to it, and the only one adjacent to it or parallel to it is pipe D, the closest one. So we have to know what D is, center-center, and then we subtract spread allowance 1, which we've already calculated. Up next, pipe D. <\/p>

Pipe D is the middle of the three-pipe parallel offset, so we have two choices of formulas. We can either know the A center-center, and then we can add spread allowance too, because when we go from A to D, the pipe is getting larger, so we're adding. Or if we want to find out D center-center, we can use the G at the bottom, center-center measurement, and subtract, because we're going from G, a bigger pipe, to D, a smaller pipe, and we'll subtract spread allowance too, because that's the spread allowance that's located in the bottom half of the offset. <\/p>

To find G, G, we only have one parallel to it really close to us, and that's D. So we'd have to know for G, we'd have to find D center, center, and then add spread allowance two. Again, going from a smaller pipe to a bigger pipe. <\/p>

At the other half of our parallel offset, to find C, the closest one adjacent to it parallel, is our F. So we need to know our F center, center, and because we are, going from F to C which is a bigger pipe we need to add and we need to add spread allowance 1 which is located on the top half. To find pipes F, the middle one, we have two choices. So we can use the center-center dimension of C which is a bigger pipe and subtract spread allowance 1 which is up in the upper half to get our F pipe which is smaller. or we can, to find F center center, we can take I, a smaller pipe, and add spread allowance two. Spread allowance two, of course, being in the bottom half and adding it. <\/p>

And lastly for I, we have one choice. We have to know the F center center and we subtract spread allowance two. To find our other three pipes, pipe B, E, and H, I'll pipe B, E, and H, center center. <\/p>

These are all our travel pieces. So they will all work out, no matter what pipe size it is, what pipe material is, to have the same center to center between 45 to 45, the same exact same measurement for all three. So our formula would be offset times 1.414. So we need to know our offset. We times that by 1.414, we'll get our center to center for B, E, and H. And we can also get our pipes B, E, and H center-center by knowing, of course, our vents and timesing it by 1.414. So we have two options there. And that's the end of the video. <\/p>"},"library":"H5P.AdvancedText 1.1","metadata":{"contentType":"Text","license":"U","title":"Text"},"subContentId":"f2e3ebe7-8955-4908-96bc-3864c0b75004"},"useSeparator":"disabled"},{"content":{"params":{"text":"

Summary<\/h2>
Understanding the 45-Degree Parallel Offset in Plumbing Tray Calculations<\/h3>
This video discusses the 45-degree parallel offset in plumbing tray calculations. The goal is to maintain the spread between all the horizontal piping throughout the offset. The spread is the distance between the center of two pipes. The spread allowance is calculated by multiplying the spread by a factor of 0.414. This allows for adjusting the length of the pipes to maintain the desired spread. The spread allowance is calculated separately for the top and bottom halves of the offset. The formula for finding the center-to-center measurement of each pipe depends on whether it is a larger or smaller pipe in relation to the adjacent pipes. Travel pieces have the same center-to-center measurement, which is calculated by multiplying the offset by 1.414.<\/p>"},"library":"H5P.AdvancedText 1.1","metadata":{"contentType":"Text","license":"U","title":"Summary"},"subContentId":"e87a0b77-411a-4798-a41f-1da0c437817a"},"useSeparator":"auto"}]},"library":"H5P.Column 1.18","subContentId":"7ef482d7-f479-4a76-a36f-a9ce00a3f687","metadata":{"contentType":"Column","license":"U","title":"Summary"}}],"behaviour":{"baseColor":"#5463d5","defaultTableOfContents":false,"progressIndicators":true,"progressAuto":true,"displaySummary":true,"enableRetry":true},"read":"Let\u2019s start!","displayTOC":"Display 'Table of contents'","hideTOC":"Hide 'Table of contents'","nextPage":"Next page","previousPage":"Previous page","chapterCompleted":"Page completed!","partCompleted":"@pages of @total completed","incompleteChapter":"Incomplete page","navigateToTop":"Navigate to the top","markAsFinished":"I have finished this page","fullscreen":"Fullscreen","exitFullscreen":"Exit fullscreen","bookProgressSubtext":"@count of @total pages","interactionsProgressSubtext":"@count of @total interactions","submitReport":"Submit Report","restartLabel":"Restart","summaryHeader":"Summary","allInteractions":"All interactions","unansweredInteractions":"Unanswered interactions","scoreText":"@score \/ @maxscore","leftOutOfTotalCompleted":"@left of @max interactions completed","noInteractions":"No interactions","score":"Score","summaryAndSubmit":"Summary & submit","noChapterInteractionBoldText":"You have not interacted with any pages.","noChapterInteractionText":"You have to interact with at least one page before you can see the summary.","yourAnswersAreSubmittedForReview":"Your answers are submitted for review!","bookProgress":"Book progress","interactionsProgress":"Interactions progress","totalScoreLabel":"Total score","a11y":{"progress":"Page @page of @total.","menu":"Toggle navigation menu"}}
