Please with proper solution. Thanks An R-22 compressor has a 5 percent clearance volume and a displacement rate of 80 L/s and pumps against a condensing temperature of 40°C. For the two different evaporating temperatures of +10 °C, compute the refrigerant flow rate in kg/s assuming that the clearance volumetric efficiency applies.
Benzene at 20 0C is pumped from one storage tank to a reactor (density=878 kg/ m3 ). Volumetric flow rate of benzene is 9.5x 10-4 m3 /s. The difference in the elevations of the two unit is 40m. The tank whichserves as a source is open to the atmosphere while the tank which receives the benzene has a pressure of P2 kPa abs in the vapor space above the benzene. 1‐in, schedule‐40 steel pipe and 2‐in Sch‐40 steel pipe isused in suction and discharge line respectively. Total friction loss of the system given as 135 J/kg . Pressure gauges in the pipeline at the inlet and outlet of the pump read (P3) 34.5kPa and (P4) 1051.6kPa, respectively.
