Question

Air at a temperature of 278 K, pressure 101.3 KPa and Mach 3 flows through frictionless pipe. Heat is transferred to the air, decelerating it to Mach 1.5. What are the resultant temperature, pressure and density? Assuming that the shock does not form, find the maximum heat interaction per unit mass of flow and determine the temperature, pressure and density at the exit. Assume the air behaves as a perfect gas with constant specific heats (Calorically perfect gas)

Answer 1

Answer:

Solution: For argon, take k = 1.67 and R = 208 J/kg⋅K. Determine the Mach ... Estimate (a) the pressure in the tank; and ... Work our way to 1 and 2 at the shock and thence to 3 in.
