A refrigeration system cools a brine from 20 C to -5 C at a rate of 30 kg/s. heat is discarded to the atmosphere at a temperature of 25 C. The specific heat of the brine is 4.5 kJ/kg-K. a. What is the ideal rate of heat removal (kW) from the system? b. What is the ideal power requirement (kW)? c. If the thermodynamic efficiency of the system is 0.37, what is the actual power requirement and heat removal rate
