The flow rate required to yield a specified reading on an orifice meter varies inversely as the square root of the fluid density:
V2(cm^3/s)=V1(cm^3/s)(Density1/Density2)^(1/2)
a) Suppose an orifice meter calibrated with nitrgoen at 25 degrees celcius and 758 mmhg is used to measure the flow rate of a process stream of hydrogen at 50 degrees celcius and 1800 mmhg, and the value read from the calibration chart is 350 cm^3/s. Calculate the true volumetric flow rate of the gas.
b) Repeat part (a), only suppose the process fulid contains 25 mole % CH4 and the balance C3H8.
