Problem #1 A centrifugal fan is to be used to take a flue gas at rest having a temperature of 352.5 K and a pressure of 749.3 mmHg and discharge this gas at a pressure of 800.1 mmHg and a velocity of 38.1 m/s. The volumetric flowrate of the gas is 56.6 std m/min*. Calculate the power input required by the fan if its efficiency is 65% and the gas has a molecular weight of 30.7. *Note: std m³/min is the volumetric flowrate of the gas if it were at 70°F and atmospheric pressure.
