Conversion confusion: Rankine in ideal gas constant

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 ... WebThe ideal gas law is: pV = nRT , where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K . For air, one mole is 28.97 g (=0.02897 kg), so we can do a unit conversion from moles to kilograms. = 8.314 philhealth register online
