At steady state, a refrigeration cycle maintains a clean room at 55oF by removing energy entering the room by heat transfer from adjacent spaces at the rate of 0.12 Btu/s. The cycle rejects energy by heat transfer to the outdoors where the temperature is 80oF.
(a) If the rate at which the cycle rejects energy by heat transfer to the outdoors is 0.16 Btu/s, determine the power required, in Btu/s.
(b) Determine the power required to maintain the clean room's temperature by a reversible refrigeration cycle operating between cold and hot reservoirs at 55oF and 80oF, respectively, and the corresponding rate at which energy is rejected by heat transfer to the outdoors, each in Btu/s.
Estimate the mass of the gas in the tank in kg assuming the gas behaves as an ideal gas. If the gas warms up to 35 deg C as it sits in the sun all day, what would the pressure rise to?
Wheel of radius r is driven by an arm OA. It is driving (without slip) wheel of a radius r2 which is fixed to a drum of radius r1. Load G is attached to the rope which winds on the drum. Calculate the speed of load G if the arm OA moves at n rev/m..
