R constant rankine
WebHow many R in 1 Celsius? The answer is 1.8. We assume you are converting between degree Rankine and degree Celsius. You can view more details on each measurement unit: R or Celsius. The SI base unit for temperature is the kelvin. 1 kelvin is equal to 1.8 R, or 1 Celsius. Note that rounding errors may occur, so always check the results. WebThe PV/T relationship of the ideal gas law holds true for a constant amount of gas. In the Rankine cycle you are always venting gas (to the turbine). Heat is added to generate more steam (pressure) to make up for the steam being consumed by the turbine to maintain a constant supply pressure to the turbine. My nuclear boiler maintains constant ...
