A factory has a large liquid propane storage tank. The propane is to be used as vapor. Evaporation of the liquid propane at -42 oC into vapor requires an external heat transfer input of 777,000 kJ. A power cycle steadily generating 55 kW of electricity at thermal efficiency of 20% is installed to supply the required propane heat transfer. Heat transfer absorbed from the surrounding 300 K atmosphere completes the cycle. NOTE: The cycle absorbs heat transfer from the 300 K (hot) environment and heat is transferred into the (cold) propane.

Include a complete schematic diagram in your write-up clearly showing hot (top) & cold (bottom) regions and arrows showing all energy exchanges.

Find the elapsed time to vaporize the propane and total work produced. Also find theoretically maximum possible total work output for the given QCOLD, WREV,MAX.
