A water fountain consume 24.1 amps (operating at 110 V) to chill water from 23 C to 5 C. It is known that heat is rejected from the unit at a rate of 9.5 kW. Assuming steady flow operation and constant specific heat for water (at 25 C) determine the following:
a) The COP of the refrigeration unit
b) The flow rate of water (in liters per minute)
