2. The following results were obtained when a sample of gas was tested in a Junker's gas calorimeter: Gas burnt = 0.03 m Gas pressure = 54.4 mm of water Barometer reading = 750 mm of Hg Gas temperature = 27C| Water temperature at inlet = 28C Water temperature at outlet = 40C Mass of cooling water = 10 kg Steam condensed during the test = 0.025 kg Determine the HCV and LCV of the gas at 15C and at 760 mm of Hg. [Specific gravity of Hg is 13.6]
