a) Air enters an adiabatic nozzle steadily at 300kPa,207C, and 50m/s and leaves at 100kPa and 180m/s. The inlet area of the nozzle is 120cm2. Determine: i. The mass flow rate through the nozzle (3 marks) ii. The exit temperature of the air (7 marks) b) Steam steadily enters a turbine through a pipe with a 150mm diameter. The inlet steam is at 20MPa and 600C with a velocity of 90m/s. The exit pipe diameter is 600 mm and the steam exits at 300kPa and 150C. Determine i. The mass flow rate of the steam ii. The steam exit velocity
