Pressurized water (pin= 10 bar, Tin= 110°C) enters the bottom ofan L= 10-m-long vertical tube of diameter D= 88 mm at a mass flowrate of mË™â¢= 1 kg/s. The tube is located inside a combustionchamber, resulting in heat transfer to the tube. Superheated steamexits the top of the tube at Pout= 7 bar, Tout= 600°C. Determinethe change in the rate at which the following quantities enter andexit the tube: (1) the combined thermal and flow work, (2) themechanical energy, and (3) the total energy of the water. Also, (4)determine the heat transfer rate, q.
Hint: Relevant properties may be obtained from a thermodynamicstext.
ANSWERE ALL BELOW Qs PLEASE!!
a) What is the outlet specific volume, in m3/kg?
b) What is the outlet velocity, in m/s?
c) What is the change in specific enthalpy from inlet to outlet,in kJ/kg?
d) Solve for the rate of change in the combined thermal and flowwork energy from inlet to outlet, in MW.
e) Solve for the rate of change in mechanical energy from inletto outlet, in MW.
f) What is the total heat transfer rate from the pipe, inMW?
