8.1 water is the working fluid in an ideal rankine cycle. the condenser pressure is 8 kpa, and saturated vapor enters the turbine at 11 mpa. determine the heat transfer in kj per kg of steam flowing, for the working fluid passing through the boiler and condenser and calculate the thermal efficiency.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.
