**drwls**, Saturday, December 8, 2012 at 11:09am(1) There are 7.48 ft^3 in a gallon. Therefore the volume flow rate can be expressed as 75 gallon/min/7.48 gal/ft^3 = 10.03 ft^3/min

Multiply that by the density of water, 62.4 lbm/ft^3, and you get 626 lbm/min.

(lbm stands for pounds mass; the preferred mass unit in the British system is slugs)

(2) Time = Volume/Flow rate

= (pi/4)*D^2*L/10.03 ft^3/min

= 94.0 minutes
