Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

333333

Consider a steam power plant that operates on the ideal regenerative
Rankine cycle with a closed feedwater heater. The plant maintains the
turbine inlet at 5000 kPa and 400; and operates the condenser at 20 kPa.
Steam is extracted at 1600 kPa to serve the closed feedwater heater,
which discharges into the condenser after being throttled to condenser
pressure. Calculate the (a) work produced by the turbine, (b) the work
consumed by the pump, (c) heat supply and the (d) thermal efficiency.
