The design product will be a description of the most efficient thermodynamic cycle required to supply 750 MW of electric power. Maximum efficiency is achieved by determining the best pressure at which to operate flash evaporator (2, 3, 7, 8) within the limits imposed by the specified parameters.

You should provide:

1. temperature, pressure, and entropy at the state points;

2. overall flow rate of water through the nuclear reactor;

3. heat transfer in the nuclear reactor;

4. % of the overall flow rate passing through the steam turbine;

5. power required for condensate pump 1;

6. power required for condensate pump 2;

7. cooling water flow rate.

Situation: Attached
Diagram: Attached

Water is used as the working fluid of a pressurized-water nuclear power plant (shown in the figure) designed to produce 750 MW of electric power. Saturated liquid exiting the reactor enters a flash evaporator at a selected pressure. The pressure reduction is achieved by a constant enthalpy throttle valve. Thus, a fraction of the water flashes into saturated steam (state 2) and the remainder flows as liquid into the mixing chamber (state 3, p3=p2). The steam enters the turbine,

The difference between the dual split Master cylinder and diagonal split Master cylinder is dual split it makes power brakes less prone to failure while diagonal split is when the left rear and right front brakes are on one hydraulic line while the right front and left rear brakes are on another.

The distinction between a diagonal split and a dual split master cylinder Power brakes are less likely to fail when the master cylinder is dual split, while diagonal splitting occurs when the left rear and right front brakes are connected to one hydraulic line while the right front and left rear brakes are connected to another.

The hydraulic pump in a car's braking system, which includes a cylinder and one or more pistons and pushes hydraulic fluid under pressure to the brakes at each wheel, is activated by pressing the brake pedal.

In order to convert the pressure on the brake pedal to hydraulic pressure, the master cylinder, also known as the master brake cylinder, feeds brake fluid into the brake circuit and regulates this in accordance with the mechanical force.
