Question details

KZH20e)>= 9.89 cal/mol.K 〈Cp.c(s) = 0.4 cal/mol.K A central power plant is a heat engine operating betwe temperature of the coal furnace and the surrounding, represented by river. Consider the coal power plant generatin kW for which the furnace temperature is 586 K and a river is a with a water temperature of 293 K. o) What is the maximossible efficiency of the plant (b) What is the minimum amount of the heat that must be d to the river? [5] (c) If the actual efficiency is 60% of the maximum efficien much heat must discard into the river? [10]
