Dry saturated steam at 0.8MPaflows through a nozzle with a throat radius of 4.545mm. The outlet pressure is 300kPa. Actual nozzle expansion, and ideal expansion, due to specific enthalpy change were both determined to be 149.10kJ/kgand 171.10kJ/kgrespectively. (Note: Use only Steam Table from the Academic Supplement as required). (1) Determine the throat or critical pressure, in kPa. (2) What type of nozzle is required? (3) Determine the nozzle efficiency in percent. (4) Calculate the velocity ratio in percent (5) The ideal or isentropic dryness fraction in percent (6) Find the outlet velocity, in m/s(7) Calculate the mass flow rate, in kg/h
