A student proposes a complex design for a steam power plant with a high efficiency. The power plant has several turbines, pumps, and feedwater heaters. Steam enters the first turbine at T1 (the highest temperature of the cycle) and saturated liquid exits the condenser at T7 (the lowest temperature of the cycle). The rate of heat transfer to the boiler (the only energy input to the system)is Qb. Determine the maximum possible efficiency and power output for this complex steam power plant design.

Hello your question lacks some values here are the values

T1 = 500⁰c,  T7 = 70⁰c, Qb = 240000 kj/s

answer : A)  56%

               B) 134400 kw ≈  134.4 Mw

Explanation:

Given values

T1 (tmax) = 500⁰c = 773 k

T7(tmin) = 70⁰c = 343 k

Qb = 240000 kj/s

A) Determine the maximum possible efficiency

= 1 - * 100

       = 1 - ( 343 / 773 )

       = 1 - 0.44 = 0.5562 * 100 ≈ 56%

B) Determine the power output for this complex steam power plant design

= Qb * max efficiency

      = 240000 kj/s * 56%

      = 240000 * 0.56 = 134400 kw ≈  134.4 Mw
