Rate of Effusion Problems
The average molecular speed in a sample of He gas at a certain temperature is 1.37x10 m/s. The average molecular speed in a sample of Kr gas is m/s at the same temperature. The rate of effusion of CH4 gas through a porous barrier is observed to be 3.73 x 10-4 mol/h. Under the same conditions, the rate of effusion of N2 gas would be mol/h.

Problem 4.024 SI Nitrogen, modeled as an ideal gas, flows at a rate of 3 kg/s through a well-insulated horizontal nozzle operating at steady state. The nitrogen enters the nozzle with a velocity of 20 m/s at 500 K, 400 kPa and exits the nozzle at 100 kPa. To achieve an exit velocity of 500 m/s, determine: (a) the exit temperature, in K. (b) the exit area, in m2.

In a gas turbine, gas enters the turbine at a temperature of 600'C and 5 bar of pressure and exit at a pressure of 1 bar. This process is an adiabatic process but the change in entropy is 0.250 kJ/kg K. Determine the temperature of exit gas. Assumed that the gas is an ideal gas and take the value of y=1.3 and cp = 1.11 kJ/kg K. Sketch the process on a T-s diagram. Determine the temperature of the exit...
