A concentrating solar collector system, as below, provides energy by heat transfer to a power cycle at a rate of 2 MW. The cycle thermal efficiency is 36%. Determine the power developed by the cycle, in MW. What is the work output, in MW*h, for 4380 hours of steady-state operation? If the work is valued at $0.08/kW-h, what is the total dollar value of the work output?
Problem 2) A heat pump cycle whose coefficient of performance is 2.5 delivers energy by heat transfer to a dwelling at a rate of 20 kW. (a) Determine the net power required to operate the heat pump, in kW. (b) Evaluating electricity at $0.08 per determine the cost of electricity in a month when the heat pump operates for 200 hours. Problem 3) A power cycle receives energy by heat transfer from the combustion of fuel at a rate of 300 MW. The thermal efficiency...
