Question

Wed Name After being underneath your refrigeration machine, you will investigate the temper ature drop across a throttle. Three fluids will be considered, mass flowrate at 0.06 kg /sec with pipe diameter 0.02 nm Saturated liquid @ 800 kPa throttle device P2 200 kPa a) working fluid is R 134 velocity at the inlet Change in Kinetic energy outlet b) fluid is now steam Velocity at the inlet V 1 = Change in Kinetic energy - outiet c) working fluid is now air with T1 470 C and P 800 kPa velocity at the inlet V 1 Kinetic energy 1 KE2 Your best estimate of the final temp T2 =
