Hydraulics Equations

Question 1

Pressure P converted to FT of any fluid

Answer 1

P = (ro)gh — or h = P/((rog) = 2.31P/SG

Question 2

Pressure P converted to FT of water

Answer 2

h = 2.31*P

Question 3

Flow to velocity

Answer 3

Q = A * v

Question 4

Darcy Loss Eq for Turbulent Flow

Answer 4

hf = (fLv^2)/(2Dg)

Question 5

Extended Bernoullis Energy Eq

Answer 5

P1/ro + (V1^2)/2 + Z1g + Ea = P2/ro + (V2^2)/2 + Z2g + Ee + Ef + Em

Question 6

BHP to Q and h

Answer 6

BHP = EFFp * WHP = EFFp * (HQSG/3960) NOTE SG

Question 7

T(ft-lb) from BHP

Answer 7

T(ft-lb) = 5252*BHP/N
