Consider the tube and inlet conditions of Problem 1.36. 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 flow work,
(c) Mechanical energy, and 

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

Data From Problem  1.36

Pressurized water (p_in = 10 bar, T_in = 110°C) enters the bottom of an L = 10-m-long vertical tube of diameter D = 100 mm at a mass flow rate of m = 1.5 kg/s. The tube is located inside a combustion chamber, resulting in heat transfer to the tube. Superheated steam exits the top of the tube at p_out = 7 bar, T_out =
600°C. Determine the change in the rate at which the following quantities enter and exit the tube: 

(a) The combined thermal and flow work, 

(b) The mechanical energy, and 

(c) The total energy of the water. Also, 

(d) Determine the heat transfer rate, q.
