Water is boiled at 1 atm pressure in a 17.36-cm-internal-diameter stainless steel pan on an electric heater. If it is observed that the water level in the pan drops by 0.083 cm in 14.004 min, determine the rate of heat transfer to the pan in watts (give your answer with 3 decimals, do NOT enter units!!!).

An air compression refrigeration system is to have an air pressure of 100 psia in the brine tank and an allowable air temperature increase of 60°f for standard vapor compression cycle temperatures of 77 f entering the expansion cylinder and 14 f entering the compression cylinder, calculate the coefficient of performance a. 2.5 b 3.3 c. 4.0 d. 5.0
