The combustion of a new fuel that is a mixture of a liquid hydrocarbon and hydrogen gas is to be modeled as a single hydrocarbon. An Orsat analysis of the dry exhaust products of this new fuel shows 6.00% CO, 6.00% O2, and 88.0% N2(no CO2 is present). Determine
a. The fuel model (CnHm) of this mixture.
b. The percentages by mass of carbon and hydrogen present in the mixture.
c. The mass air/fuel ratio used in the combustion process.
d. The dew point temperature of the exhaust products at 0.152 MPa.
A 1-in. thick steel plate measuring 10 in. in diameter is heated from below by a hot plate, its upper surface exposed to air at 80oF. The heat-transfer coefficient on the upper surface is 5 Btu/h ftoF and k for steel is 25 Btu/h ftoF.
