Refridgerant-134a with a flow rate of 0.12 kg/s is cooled to 40 degrees C at constant pressure in a condenser by using cooling water. Initially the refrigerant is at 1,200 kpa and 50 degrees C. Estimate the heat removed by the cooling water.

Expert Solution

temperature change of the refrigerant=T=50 C-40 C=10C

mass of refrigerant=0.12 kg/s

Heat removed by cooling water =mass *specific heat of water*T=0.12kg/s*4.186 J/g C*10C

=0.12*1000 g/s*4.186 J/g C*10C

=5023.2J/s

=5.023 KJ/s (rate of removal of heat by cooling water)

1. Water at a flow rate of = 0.25 kg/s is cooled from 70 C to 30 c by passing it through a thick-walled tube of internal diameter of Di =50 mm and an external diameter of D = 60 mm. Hot Water is cooled by blowing cold air at T? = 15 C in cross flow over the tube. Velocity of the air over the tube is 20 m/s. Evaluating the water properties at 325 K from Table A.6...

A compressor receives 0.1 kg/s R-134a at 150 kPa, -10 degrees C and delivers it at 1000 kPa, 40oC. The power input is measured to be 3 kW. The compressor has heat transfer to air at 100 kPa coming in at 20 degrees C and leaving at 25 degrees C. I'm trying to find the mass flow rate of air, BUT can you please just show me the energy balance and Schematic to set this up. JUST the energy balance...
