The fluid is then cooled reversibly at constant pressure until the piston regains its original position heat is then supplied reversibly with the piston firmly locked in position until the pressure rises to the original value of 20 bar. The fluid is allowed to expand reversibly behind a piston according to a law pV2 = C until the volume is doubled. (b) Mean specific heat of the gas, cn:(a) Heat transferred, Q :A cylinder contains 1 kg of a certain fluid at an initial pressure of 20 bar. Change in temperature of the gas = 25C to 125C The specific heat capacity of the system during a certain process is given by : If the mass of the gas is 6 kg and its temperature changes from 25C to 125C find : a. Find the absolute pressure of steam.Solution. The atmospheric pressure is 760 mm of Hg. Some of steam in the pipe condenses in the manometer arm connected to the pipe. The level of mercury in open arm is 97.5 mm greater than that in the arm connected to the pipe.
