6 -) Ball 'A' is released from rest at a height of 20m. After 1 second, a
second ball 'B' is thrown upward from the ground. If the two balls
pass one another at a height of 6m, determine:

(i) speed at which the ball B was thrown upward,
(ü) speed of each ball when they pass​

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.
