Unformatted text preview: 4. Steam enters an adiabatic turbine at 2 MPa, 300 ◦ C and exits at 50 kPa. The mass ﬂow rate through the turbine is 2 kg/s, and the turbine produces a power output of 1350 kW. Calculate the exit temperature and the exit quality, if saturated. 5. A mass ﬂow of 3 kg/s of saturated liquid water at 2 MPa enters a 5–cm diameter boiler pipe. The water exits at 2 MPa pressure. The rate of heat transfer to the water is 7780 kW. (a) Neglecting KE at the exit, calculate the exit temperature and exit speciﬁc volume. (b) Use the result in a), along with the given mass ﬂow and pipe diameter, calculate the exit velocity. Should KE be included at the exit. (c) Using your result from b) as an estimate of the exit velocity, recalculate the exit temperature....
