Consider the tube and inlet conditions of Problem 1.30. Heat transfer at a rate of q = 3.89 MW is delivered to the tube. For an exit pressure of p = 8 bar, determine (a) the temperature of the water at the outlet as well as the change in

(b) combined thermal and fow work,

(c) mechanical energy, and

(d) total energy of the water from the inlet to the outlet of the tube.

Hint: As a first estimate, neglect the change in mechanical energy in solving part (a). Relevant properties may be obtained from a thermodynamics text
