Answer 2

Answer:

E = 15/0.15 = 100

Explanation:

Rankine cycle efficiency:

The overall thermal efficiency of current nuclear power plants using the Rankine cycle is around one-third (33%); hence, 3000 MWth of thermal power from the fission reaction is required to produce 1000 MWe of electrical power.

According to the average steam system, thermal cycle efficiency of 56.3%, 43.7 percent of the energy used in the boilers is lost or squandered. Every business will have a small number of acceptable losses, but the majority of losses may be avoided or reduced.

The Rankine Cycle's Thermal Efficiency:

The thermal efficiency, ηth, represents the fraction of heat, QH, converted to work. ...

DH = DQ → Q = H2 – H1

dH = Vdp → W = H2 – H1 ...

By dividing by the mass, the enthalpy may be converted into an intense or particular variable.

steam rate estimation:

• Steam mass flow and blowdown rate may be used to compute feedwater flow rate:
• Feedwater Mass Flow * Blowdown Rate = Blowdown Mass Flow.
• Feedwater mass flow minus blowdown mass flow equals steam mass flow.
• Feedwater Mass Flow - Feedwater Mass Flow * Blowdown Rate equals Steam Mass Flow.
