Air, with a pressure of 98.5 kPa and a temperature of 22.0°C, flows through a square duct at 15.0 m/s. Each side of the duct has a length of 15.0 cm. (a) Determine the volumetric flow rate and the mass flow rate of the air. For parts (b) and (c), you should develop a model for the duct in the program. (b) Plot the volumetric flow rate and the mass flow rate of the air for air pressures ranging from 98.5 kPa to 500 kPa, while the temperature is maintained at 22.0°C. (c) Plot the volumetric flow rate and the mass flow rate of the air as the pressure is maintained at 98.5 kPa, but as the temperature varies from 22.0°C to 150.°C.
Given: Air, P = 98.5 kPa, T = 22.0°C = 295 K; V = 15.0 m/s; L = W = 15.0 cm = 0.15 m What will be an ideal response?
