14. The flow water in a 10-in Schedule 40 pipe is to be metered. The temperature of the water is
100oF, and the static pressure upstream of the meter is 20 psig, The density of the water is 62
Ibm/ft3
, Assume the flow meter is a square-edged orifice with a diameter ratio of 0.5 . When the
flow rate is 1,200 gpm and the flow coefficient is 0.5. the pressure drop across the orifice
(ibf/in2
) is Pipe ID = 10.002 in.
