An orifice meter with a 5 cm diameter is used to measure the flow rate of liquid. Under a head of 4 m, the velocity of the liquid at vena contracta is 7.5 m/s. If the actual discharge through the pipe is 8 l/s, calculate the coefficients of velocity, discharge, and contraction.  Answers should be : Cv= 0.85 Cd= 0.46 Cc= 0.54
