A rectangular classroom is to be designed so that it has a total volume of 4000 cubic feet. It must be designed to minimize heat loss. Since warm air rises the heat loss throught the ceiling is 4 times the heat loss through the floor. Th heat loss through any interior wlave is tiwce the heat loss throguh the lfoor. The loss through the outer walls is 3 times that throguh the floor the ceiling must be 10 feet high according to the local building coeds.
Required:
Find the dimensions of the room that minimzie the heat loss assume the room justs out form the rest of the building.

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.

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
