Orifice meter with an orifice diameter of 25 cm is used to

measure the flow rate of water at 25°C in a 70 cm diameter

pipeline. If the water flow rate is 500 L/s, determine the

following:

a) Pressure difference indicated by the pressure gauge

for this flow rate (in kPa).

b) The head loss of the orifice meter (in m)

c) If a manometer is connected to the orifice and

measures 40 cm of mercury height, what is the

flow rate (in L/s) in the pipe.
