Alaboratory in the y building keep a vacuum pressure of 0.1 kpa abs. what is the net force acting on the door considering the atmospheric pressure in mt. helen campus is 101.325 kpa abs. (assume the dimensions of door is 2 m x 0.5 m).

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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.
