Air is compressed by a 15-kW compressor from P1 to P2. The air temperature is maintained constant at 258C during this process as a result of heat transfer to the surrounding medium at 208C.
Determine the rate of entropy change of the air. State the assumptions made in solving this problem.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?
