Code the following Engineering problems in python to get the solution:
Case 1.) Air flows through the supersonic nozzle. The inlet conditions are 7 kPa and 420°C. The nozzle exit diameter is adjusted such that the exiting velocity is 700 m/s. Calculate (a) the exit temperature, (b) the mass flow rate, and (c) the exit diameter. Assume an adiabatic quasiequilibrium flow
Case 2.) Liquid sodium, flowing at 100 kg/s, enters a heat exchanger at 450°C and exits
at 350°C. The Cp of sodium is 1.25 kJ/kg·°C. Liquid water enters at 5000 kPa
and 20°C. Determine the minimum mass flow rate of the water so that the water
just vaporizes. Also, calculate the rate of heat transfer.
Case 3.) A Carnot engine operates between two temperature reservoirs maintained at
200 and 20°C, respectively. If the desired output of the engine is 15 kW, determine
the QH and QL
