Consider the system below, with weight m hanging from a rope. given: d1=192 cmd2=172.8 cmd3=19.2 cmd4=19.2 cmd5=28.8 cmm=43 kgdetermine the reactions at a, b, and c.

The temperature of air decreases as it is compressed by an adiabatic compressor. 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.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
