Question

At steady state, a 750MW power plant receives energy by heat transfer from the combustion of fuel at an average temperature of 367deg C. The plant discharges energy by heat transfer to a river whose mass flow rate is 1.65 imes 10^(5)k(g)/(s). Upstream of the power plant the river is 17deg C. You may assume a constant specific heat for the river. River, tilde(m)=1.65 imes 10^(5)k(g)/(s) (a) Determine the increase in the temperature of the river Delta T due to the heat transfer in deg C if the thermal efficiency of the power plant is the Carnot efficiency between 367deg C and 17deg C. (b) Determine the increase in the temperature of the river Delta T due to the heat transfer in deg C if the thermal efficiency of the power plant is two-thirds of the Carnot efficiency. (c) Discuss what your answers imply. (d) Is it valid to assume a constant specific heat for the river? Explain. an average temperature of 367C.
