How to find the volume of a cyclinder when your just given the diameter of 70 feet
So how could i find the height whem all i have is the diameter? I know my diameter is 70 which would make my radius 35 but not sure how to figure height out
The diameter isn't related to the height.....the height might be any positve value....
Thus......the volume depends on both the diameter and height ....
My questiom is a 70 foot diameter clarifier drops 5 inches in 15 minutes during a calibration test on a was pump. Calculate the was pumping rate in gallons per minute. It says to convert the inches into feet and divide by the time it took for it to drop
OK....we have something we can work with
5 inches = 5/12 ft
The volume of water drained is given by:
pi * (diameter/2)^2 * (height) =
pi * ( 70/2)^2 (5/12) = 6125 * pi / 12 cubic ft of (water??)
If we're talking abbout water...we need to know how many gallons of water are in a cubic ft
1 ft^3 water ≈ 7.48051948 gal of water
So...the total gallons drained ≈ (7.48051948) 6125 * pi / 12 ≈ 11995 gal
Divide this by 15 and we get that about 800 gals are drained per minute
