Saturated liquid water at 1 MPa enters a D = 5 cm pipe at a rateof m(dot) = 2 kg/s. Heat is transferred to the water at a rate ofQ(dot) = 5000 kW. The exit is at 1 MPa pressure.
(a) Neglecting kinetic energy, calculate the temperature at thepipe exit. (ans = 400â—¦C)
(b) Using your answer in a), calculate the exit velocity of thewater. (ans = 312 m/s)
(c) Based upon your answer, should kinetic energy be included inyour analysis? (ans = probably)
(d) Including the exit kinetic energy, recalculate the exittemperature. Iterate this procedure a couple of times. (ans =378â—¦C)
