1. A convergent nozzle with an exit diameter of 1 in. has an air inlet flow of 68 F, 14.7 lbf/in.2 (stagnation conditions). The nozzle has an isentropic efficiency of 95%, and the pressure drop is measured to be a 20-in. water column. Find the mass flow rate, assuming compressible adiabatic flow. Repeat this calculation for incompressible flow.
2. Develop a program that calculates the stagnation pressure and temperature from a static pressure, temperature, and velocity. Assume the fluid is air with constant specific heats. If the inverse relation is sought, one of the three properties in the flow must be given. Include that case also.
