A power cycle receives energy by heat transfer from the combustion of fuel at a rate of 300 MW. The thermal efficiency of the cycle is 33%.

a.) Determine the net rate at which power is developed in MW.
b.) For 8000 hours of operation annually, determine the net work output in kW-h/yr.
c.) Evaluating the net work output at $0.08 per kW-h, determine the value of the net work in $/yr.
