A mass of 100 kg of a liquid food contained in a large vessel is to be cooled from 40°C to 5°C in 10
A bulk of 100 kg of a melting subsistence contained in a large vessel is to be cooled from 40°C to 5°C in 10 min. The particular intensity of the melting subsistence is 3600 J/(kg°C). Cooling is produced by immersing an evaporator contortion inside the melting. The evaporator contortion sphere is 1°C, and condenser sphere is 41°C. The refrigerant entity used is R-134a. Draw the composure cycle on a pressure–enthalpy diagram and use the refrigerant property tables to reresolve the aftercited talents of this problem:
a. Show the composure cycle on a pressure–enthalpy diagram for R-134a.
b. Determine the stream scold of R-134a.
c. Determine the C.O.P. for the scheme.
