1 Water enters a continuous flow gas calorimeter at 65 °F and leaves at 95 °F. During a five minute run 0.253 ft 3 of natural gas is burned at 70°F and 0.04 inHg (gage pressure). Also, 6200 grams of heated water and 9.5 grams of condensate are collected. Room and shell temperatures are measured at 71 °F and 75 °F respectively. Assuming the average specific heat of water is 1 Btu/lbm OF and neglecting Ct correction what are the HHV and LHV of gas in Btu/ft 3 at ASTM standard (60°F and 30 inHg) Hint: First calculate V_s (Volume of gas at ASTM standard) 9 Atmospheric pressure (absolute) = 29.98 inHg Saturated pressure of water vapor at 600F= 0.52 inHg Saturated pressure of water vapor at 70°F= 0.74 inHg Convective heat transfer coefficient of the calorimeter (h_c) = 5 Btu/ft² hr OF The calorimeter surface area = 2.1 ft² Latent heat of water (h_f) at 60°F = 1059 Btu/lbm 1 Water enters a continuous flow gas calorimeter at 65 °F and leaves at 95 °F.
