1. Convert 8720 gallons per minute to ft3/sec.
2. One gallon is a volume measure of 231 in3. Determine the velocity in a pipe 2" in diameter when water flows at the rate of 20 gpm in the pipe.
3. Oil for a hydraulic system (sg = 0.90) is flowing at .10 ft3/sec. Calculate the weight flow rate.
4. A reservoir contains 1000 gal of water. If a pump can pump at the rate of 4 lb/mm, how long will it take for the tank to empty?
5. What is the velocity in a half-inch hose with a flow of 10 gpm?
