Conversions

7.48 gallon = 1.0 ft3 1 gal = 3.7854x10-3 m3

1 MGD = 694 gal/min = 1.547 ft3/s = 43.8 L/s

1 ft3/s = 449 gal/min

g = 32 ft/s2

W= = 62.4 lb/ft3 = 9.8 N/L

1 hp = 550 ft-lbs/s = 0.75 kW

1 mile = 5280 feet 1 ft = 0.3048 m

1 watt = 1 N-m/s

1 psi pressure = 2.3 vertical feet of water (head)

At 60 F, ν = 1.217 x 10-5 ft2/s
