MCQ : Compressible flow

Nitrogen is escaping from a pressurized bottle (internal temperature 300 K, internal pressure 650 kPa) through an open valve that happens to be shaped like a converging-diverging nozzle, with an area ratio of 10 on the diverging side of the throat. What area ratio at the shock is required to get the exit pressure from the nozzle to equal atmospheric pressure (100 kPa)? (It’s a fairly complex calculation, so your answer may differ by 1 or 2 in the least significant figure shown.) a)1.53 b)8.32 c)8.67 d)9.62

Nitrogen (N2), at 300 K, 1 bar with a mass flow rate of 1 kg/s enters an insulated mixing chamber and mixes with carbon dioxide (CO2) entering as a separate stream at 500 K, 1 bar with a mass flow rate of 0.5 kg/s. The mixture exits at 1 bar. Assuming ideal gas behavior, for steady-state operation, determine (a) the molar analysis (i.e., the molar flow rate for each gas) of the exiting mixture, (b) the exit mixture temperature, and...

Nitrogen (N2) at 1 bar, 300 K enters a compressor operating at steady state and is compressed adiabatically to an exit state of 16 bar, 750 K. The N2 is modeled as an ideal gas and kinetic and potential energy effects are negligible. Determine the work input, in kJ per kg of N2 flowing, the rate of entropy production, in kJ/K per kg of N2 flowing, and the isentropic compressor efficiency.

A bottle of soda with a temperature of 71° Fahrenheit was taken off a shelf and placed in a refrigerator with an internal temperature of 35° F. After ten minutes, the internal temperature of the soda was 63° F. Use Newton’s Law of Cooling to write a formula that models this situation. To the nearest degree, what will the temperature of the soda be after one hour?

Nitrogen gas is contained in a rigid 1-m3 tank, initially at 5 bar, 300 K. Heat transfer to the contents of the tank occurs until the temperature has increased to 400 K. During the process, a pressure-relief valve allows nitrogen to escape, maintaining constant pressure in the tank. Neglecting kinetic and potential energy effects, and using the ideal gas model with constant specific heats evaluated at 350 K, determine (a) the mass of nitrogen that escapes, in kg, and (b)...

Air is cooled from 300 K to 273 K as it flows steadily through a duct. Frictional dissipation may be neglected. Cooling is achieved by removing heat via a heat pump. The work requirement is 1.15 times that of a reversible heat pump operating between 263 and 310 K. For each mole of air flowing through the duct, calculate: Air can be assumed an ideal gas with a constant heat capacity cP of 3.50R. The temperature of the surroundings is...
