Afuel gas containing 86% methane, 8% ethane, and 6% propane by volume flows to a furnace at a rate of 1450 m3/h at 15°c and 150 kpa (gauge), where it is burned with 8% excess air. calculate the required flow rate of air in scmh (standard cubic meters per hour).
a certain gas has a molecular weight of 30.0, a critical temperature of 310 k, and a critical pressure of 4.5 mpa. calculate the density in kg/m5 (b) if the gas obeys the law of corresponding states of this gas at 465 k and 9.0 mpa (a) if the gas is ideal and
