6-52E Water enters an ice machine at 55"F and leaves as ice at 25"F. If the COP of the ice machine is 2.4 during this operation, determine the required power input for an ice production rate of 28 Ibm/h. (169 Blu of energy needs to be removed from each Ibm of water at 55°F to turn it into ice at 25"F.)
