Consider the transfer of 10kJ of heat between thermal reservoirsat 500 and 400K. (a) Determine the magnitude, in kilojoules, andthe direction of the availability transfer for two reservoirs. (b)Now, consider the transfer of 10 kJ of heat between thermalreservoirs at 280 and 250K. Determine the magnitude and directionof the availability transfers for these two reservoirs. (c) Comparethe direction of heat transfer versus availability transfer for thetwo processes. The environmental temperature is 298K.
