An incinerator produces a dry exit gas of the following Orsat composition measured at 600F and 30 inches of Hg absolute: 4.0% CO2, 26.0% CO, 2.0% CH4, 16.0%H2 and 52.0% N2.
A dry natural gas of the following (Orsat) composition: 80.5% CH4, 17.8% C2H6, and 1.7%N2 is used at the rate of 1200ft3/min at 600F and 30 inches of Hg absolute to burn the incineration off gas with air. The final products of combustion analyze on a dry basis: 12.2% CO2, 0.7% CO, 2.4% O2, and 84.7%N2.
Calculate (a) the rate of flow in ft3/min of the incinerator exit gas at 600F and 30 inches of Hg absolute on a dry basis
A body consists of a right circular cone whose base is 12 in. and whose altitude is 16 in. A hole 8 in. in diameter and 4 in. deep has been drilled from the base. The axis of the hole coincides with the axis of the cone. Locate the centroid of the..
