Plumbing question/suggestion

Your math is as bad as mine.lol
Dude let it go. You are using my suggestion. You are welcome.lol

 

Where is the bad math?

 

How can a pipe that is 25% bigger hold 50% more water?In my limited understanding of math. The 1" PVC is 34.5% smaller then the 1.25pvc.

 

I explained that right up there ^^^^^^^. Anyway, I never said the 1.25 inch pipe is 25% bigger than the 1 inch pipe! The inside diameter part is 25% bigger only.
Here is another example. You have a 40 inch TV, some one has an 80 inch TV. Do you think his TV is 2 times bigger than your TV or 4 times bigger?
A 9 years old kid might say 80/40=2 so his TV is 2 times bigger than your TV. It is OK for a kid to say that because he/she is a kid LOL!

Anyway, I think I will let it go as I have said enough to make a point.

 

Good you are giving me a headache.☺
Water goes on the inside of the pipe right?lol

 

The 1.25 PVC is a bit thicker than the 1.0 PVC however, not much change. Here is the math for 1.0 and 1.25

Cross section area
1 inch => (0.5*0.5)*3.14 =0.785 squared inches
1.25 => (0.625*0.625)*3.14=1.2265625 squared inches

1.2265625 - 0.785 = 0.4415625 (difference)

0.4415625 is 56% of 0.785

In reality, the 1 inch pipe has id as 1.049 and the 1.25 inch pipe has id as 1.380 (Same math applied)

 

OK, let's forget about this. When you happen to go to home depot, you will see what I mean.

 

if you are worried about noise and for your situation maybe a Maggie muffler would work? These seem to take up less space and are not as loud....

Sizing of PVC piping and fittings is very importannt. Take a look at this chart showing headloss due to friction in various sizes of PVC. Jumping from a 3/4" up to a 1" or from a 1" up to a 1.25" or 1.5" is a major improvement. The area and volume difference is just one size jump is huge. If you use 10 GPM as an example which is only 600 GPH of split the difference between 10 and 20 GPM which is 15 GPM and 900 GPH which is a very common pump size in the reef hobby you see very big changes when you step up one pipe size.

This is the stuff that keeps engineering firms like the one that employs me in business!

 

TBH, you lost me at gpm
Thanks for sharing but I am quite a blonde this morning and some how I don't think I understand what you are talking about yet. How about simple English please.
