Question: pressurized water pin 10 bar tin 110c enters the bottom...
Pressurized water (pin= 10 bar, Tin= 110°C) enters the bottom of an L= 10-m-long vertical tube of diameter D= 75 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 pout= 7 bar, Tout= 600°C. Determine the change in the rate at which the following quantities enter and exit the tube: (1) the total energy of the water. Also, (2) determine the heat transfer rate, q.
Solve for the rate of change in mechanical energy from inlet to outlet, in MW.
