Water / Pumping

1 cubic metre / sec = 13,200 gallons / min (UK gallon)
1 lb / square inch = 2.3 ft of water = 0.7 kg / sq . cm

1)  Velocity of water, V (ft / sec) = (Gallons / min) / ( 2 x D x D)
     (where, D = Pipe ID in inches)

2)  Weight of water (lbs) = D x D x L
     ( where, D = Pipe ID in inches, L = Pipe length in Yards)

3)  Water Horse Power = (G x H) / 3,300
      (where, G = Gallons/min, H = head in feet)
