Saturated liquid water at 1 MPa enters a D = 5 cm pipe at a rate of m(dot) = 2 kg/s. Heat is transferred to the water at a rate of Q(dot) = 5000 kW. The exit is at 1 MPa pressure.

(a) Neglecting kinetic energy, calculate the temperature at the pipe exit. (ans = 400◦C)

(b) Using your answer in a), calculate the exit velocity of the water. (ans = 312 m/s)

(c) Based upon your answer, should kinetic energy be included in your analysis? (ans = probably)

(d) Including the exit kinetic energy, recalculate the exit temperature. Iterate this procedure a couple of times. (ans = 378◦C)

Steam enters a horizontal 15-cm-diameter pipe as a saturated vapor at 5 bar with a velocity of 10 m/s and exits at 4.5 bar with a quality of 95%. Heat transfer from the pipe to the surroundings at 300K takes place at an average outer surface temperature of 400 K. For operation at steady state, determine (a) the velocity at the exit, in m/s. (b) the rate of heat transfer from the pipe, in kW. (c) the rate of entropy...
