So for the first part of the question, we're trying to find the volume flow rate.
00:08
So the volume flow rate kill that is equal to the velocity times the area.
00:21
And here the area is going to be the cross -sessional area of the pipe.
00:26
That times the piar squared.
00:32
So we can just, you know, do our substitution.
00:41
But let's figure out the area first.
00:43
So, you got radius.
00:48
The diameter was given us three inches.
00:50
So the radius is going to be 1 .5, right? because it's divided by 2 inches.
00:57
We need to convert that to feet.
00:59
So 1 inch, 1 inch is 2 .00.
01:10
0 .0 .0 .0 .833 feet.
01:18
So the radius, which is 1 .5 inch, is going to be.
01:25
Be equal to 1 .5 times 0 .00 0 0803 so our radius in feet is going to be 0 .195 feet okay now because our volume is in feet per second okay so we need to convert a radius to feet so once we have that, you can get the volume for the rate.
02:02
The volume was given as 10.
02:04
It's going to be pi times 0 .12495 squared.
02:20
The volume for rate is going to be, let's see.
02:30
It's going to be 0 .4 .9 .048 feet squared per second.
02:42
Or we can say i'm just approximately the 0 .49 feet squared per second so now we need to convert that to gallons per minute so let's talk about gallons per minute so one feet cube just a second this is supposed to be oops excuse me it's supposed to be cube okay not square this is volume so this fit cube per second all right so let's talk about gallons per minute so now one feet cube as we go to 7 .4841 gallons and we all know that you know one second is about you know that one second it's the same as one over 60 minutes so our volume flow rate that is going to be 0 .49 times 7 .4482 1 times 1 divided 60 minutes...
