A previously calibrated rotometer is being used to measure a gas flow. The old calibration curve is a straight line described by the following equation:
Q=1.10RR-0.50
Where
Q=flow, liters/minute
RR=rotometer readi g, dimensionless
The rotometer was calibrated using ethane (C2H6) at 1.40atm and 60*F. The gas presently bei g used is methane (CH4) at 1.10atm and 100*F.
A. Calculate the true volumetric flow rate of methane in the rotometer whe. The rotometer reads 4.0.
B. Calculate the mass flow rate of methane in g/min.
