Cycle starts at a low side pressure above 75 MPa and a low side temperature of 35 C slightly above the critical point. The fluid velocities at entry to and exit from a turbine may be quite high and the corresponding kinetic energies significant. 147 psia 408 inches of water 147 psia 299 inches of mercury 1 inch of mercury 254 millimeters of mercury 1 millimeter of mercury 103microns of mercury.

Conversion factors are listed below. Is brought to the high-side pressure of 20 MPa and a. 71 Rankine Cycle We can use a Rankine cycle to convert a fossil-fuel nuclear or solar power source into net electrical power.

In a Rankine cycle the steam at inlet to turbine is saturated at a pressure of 35 bar and the exhaust pressure is 02 bar. The most common of these are inches of water inches of mercury millimeters of mercury and microns of mercury. A typical chart covers a pressure range of 0011000 bar and temperatures up to 800 degrees Celsius.
