QUESTION 2: Turbine Steam flows steadily through a turbine. The mass flow rate of the steam entering the turbine is 15 kg/s and the velocity of the inlet is 10 m/s (state 1). The inlet conditions of the steam are 12 MPa and 455 C. Ten percent of the working fluid exits the turbine at a pressure of 1 MPa, 280 C and 20 m/s (state 2). The remainder of the working fluid exits the turbine at 8 kPa and 30 m/s (state 3). The turbine loses heat to the surroundings at the rate of 650 kW and produces work at the rate of 10 MW. Potential energy effects can be neglected. The surface temperature of the turbine is 450 K. Do the following: I. Draw a schematic of the turbine in the space below. Clearly indicate the system boundary and the direction of energy transfer by work and the direction of heat transfer between the system and its surroundings. Use the numbering for states as provided in the problem statement. QUESTION 2: Turbine Steam flows steadily through a turbine.
