Question 1169980: A pipe 8 in. in diameter is transporting water at 48 ft. per min. Determine amount (gal.) will pass a certain point per hr.
A pipe is a cylinder.
Check my calculations, please.
Volume = Pi * r^2 * length
3.1416 * 4 * 4 * 576 = 28952.98 = 28953 cu. in.
231 cu. in. = 1 gal.
28953 / 231 = 125.337 = 125 gal.
125 * 60 = 7500 gal. per hr.
