One of the calculations you will perform using the LabQuest is taking into account the increase in air pressure inside the flask as the temperature increases. The relevant formula is given in the lab manual as: P room I room Pair where Proom and Troom is the pressure and temperature of the lab room respectively. You will be required to rearrange this equation into the form Pair = AT, where A is a constant. If Proom = 104.6 kPa and...
Air enters an adiabatic nozzle at 500 kPa and a temperature of 200 °C with a velocity of 100 m/s. It exits the nozzle at a pressure of 100 kPa. Assuming that the expansion through the nozzle occurs reversibly, determine (a) the exit temperature and (b) the exit velocity of the air. The specific heats of air can be assumed to be constant with Cv = 0.742 kJ/kg oC and Cp = 1.029 kJ/kg oC.
Air enters an adiabatic nozzle under the following conditions: pressure = 900 kPa temperature = 560°C velocity = 2.7 m/s The air leaves the nozzle at 850 kPa and 480 °C. What is the velocity at the exit of the nozzle? Assume the specific heat is constant and can be taken at the average temperature between the inlet and outlet. air (c) EYES Niel Crews, 2013
