Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.14 mpa, and leaves as superheated vapor at 0.8 mpa and 60°c at a rate of 0.06 kg/s. determine the rates of energy transfers by mass into and out of the compressor. assume the kinetic and potential energies to be negligible.

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.
