Air enters the 1-m2 inlet of an aircraft engine at 100 kPa and 20°C with a velocity of 184 m/s. Determine the volume flow rate, in m3/s, at the engine’s inlet and the mass flow rate, in kg/s, at the engine’s exit. The gas constant of air is R = 0.287 kPa·m3/kg·K.
The volume flow rate at the engine’s inlet m3/s.
The mass flow rate at the engine’s exit is kg/s.
The ventilating fan of the bathroom of a building has a volume flow rate of 33 L/s and runs continuously. If the density of air inside is 1.20 kg/m3, determine the mass of air vented out in one day.
The mass of air is kg.
A steady-flow compressor is used to compress helium from 15 psia and 70°F at the inlet to 200 psia and 600°F at the outlet. The outlet area and velocity are 0.01 ft2 and 100 ft/s, respectively, and the inlet velocity is 53 ft/s. Determine the mass flow rate and the inlet area. The gas constant of helium is R = 2.6809 psia·ft3/lbm·R.
The mass flow rate is lbm/s.
The inlet area is ft2.
