Question 4 A steam turbine operates with an inlet condition of 30 bar, 400 °C, 160 m/s and an outlet state of a saturated vapour at 0.7 bar with a velocity of 100 m/s. The mass flow rate is 1200 kg/min and the power output is 10800 kW. Present the process on the T-v diagram. Determine the magnitude and direction of the heat-transfer rate in kJ/min if the potential energy change in negligible.
A fan drawing electricity at a rate of 1.5 kW is located within a rigid enclosure. The length, width and height of the enclosure are respectively equal to 5 m, 4 m, and 3 m.
