An electric plant that produces 10 x 109 kwh/year has an annual investment expenditure of $43.5 x 10/year for an expected lifetime of 25 years, with no remaining salvage value. the capital cost of the plant is repaid at 5% discount or interest rate. total annual operating cost at the plant is $20 x 106/year, and annual return to investors at 5% of the operating cost plus capital repayment cost.

(a) what is the levelized cost of electricity in $/wh?
(b) if they charge at this cost and assuming no other cost, estimate when will they reach breakeven point?
(c) if they charge at this cost and assuming no other cost, estimate the return on investment, if any?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
