Pressurized water ( 10 bar, 110°c) enters the bottom of an 10-m-long vertical tube of diameter 63 mm at a mass flow rate of 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 7 bar, 600°c. determine the change in the rate at which the following quantities enter and exit the tube: (1) the combined thermal and flow work, (2) the mechanical energy, and (3) the total energy of the water. also, (4) determine the heat transfer rate, . hint: relevant properties may be obtained from a thermodynamics text.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
