1. The problem statement, all variables and given/known data
A power cycle has a thermal efficiency of 40% and generates electricity at a rate of 100 MW. The electricity is valued at $0.08 per kW * h. Based on the cost of fuel, the cost to supply Qin is $4.50 per GJ. For 8000 hours of operation annually, determine, in $. a. The value of electricity generated per year. b. The annual fuel cost. c. Does the difference between the results of parts (a) and (b) represent profit? Discuss. 2. Relevant equations Thermal Efficiency = W cycle/ Q in 3. The attempt at a solution I don't even know where to begin. Can someone please get me on the right track.
