Pressurized water (Pin = 10 bar, Tin = 110°C) enters the bottom of an L = 12-m-long vertical tube of diameter D = 110 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 at a rate of q = 3.89 MW is delivered to the tube. For an exit pressure of Pout = 8 bar, determine (a) the temperature of the water, in °C, at the outlet as well as the change in (b) combined thermal and flow work, in MW, (c) mechanical energy, in kW, and (d) total energy of the water from the inlet to the outlet of the tube, in MW. Hint: As a first estimate, neglect the change in mechanical energy in solving part (a). Relevant properties may be obtained from a thermodynamics text.

Pressurized water (pin = 10 bar, Tin = 110°C) enters the bottom of an L = 12-m-long vertical tube of diameter D = 110 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 at a rate of q = 3.89 MW is delivered to the tube. For an exit pressure of Pout = 8 bar, determine (a) the temperature of the water, in °C, at the outlet as well as the change in (b) combined thermal and flow work, in MW, (c) mechanical energy, in kW, and (d) total energy of the water from the inlet to the outlet of the tube, in MW.
