2. Natural gas containing a mixture of methane, ethane, propane, and butane is burned in a furnace with excess air. One hundred kmol/h of a gas containing 94.4 mole% methane, 3.40% ethane, 0.60% propane, and 0.50% butane is to be burned with 17% excess air. a) Calculate the molar flow rate of the air. b) Now instead of using numerical values, we will work the problem by deriving an equation. Define the following variables: i.molar flow of the fuel gas:...

3. During an experiment involving the flow of dry air at 30°C and 1 atm (101.325 kPa) at a free stream velocity of 5 m/s over a body covered with a layer of naphthalene. The incoming air is free of naphthalene, and thus the mass fraction of naphthalene in the free stream is zero (WAC). The vapor pressure of naphthalene at 30°C is 18.5 Pa and the diffusion coefficient of naphthalene in air at 30°C is 0.86 x...
