n-Hexane is burned with excess air. An analysis of the product gas yields the following dry-basis molar composition: 6.9% CO2, 2.1% CO, 0.265% C6H14 (+O2 and N2). The stack gas emerges at 760 mm Hg. Calculate the percentage conversion of hexane, the percentage excess air fed to the burner, and the dew point temperature of the stack gas.
gold has a face centered cubic crystal structure where there are four atoms per unit cell.below is a calculated xrd
question 1a a receptionist who has been working in a large accountancy firm for eleven months has been complaining of
The March 1979 accident at the Three Mile Island nuclear plant occurred due to a series of operator errors and equipment failures, which reduced the flow of cooling water to the reactor core. As a result, the water began to boil and the core reached ..
Consider the following cyclic process carried out in two steps on a gas: Step 1: 45 J of heat is added to the gas, and 10. J of expansion work is performed. Step 2: 60. J of heat is removed from the gas as the gas is compressed back to the initial..
What results can be expected in the near-term? The mid-term? The long-term? Nanotech's development can usefully be divided into stages, for example:
A 30 mol% feed of benzene in toluene is to be distilled in a batch operation. A product having an average composition of 45 mol% benzene is to be produced. Calculate the amount of residue, assuming α = 2.5 and W0 = 100.
A storage tank is purged continuously with a stream of nitrogen. The purge stream leaving the tank is saturated with the product stored in the tank.
Calculate the rate of moisture condensation (kg/h) and the volumetric flow rate of the air drawn from the outside.
The left side of of the mechanical energy equation has three terms: P/p, (1/2)av^2 and gz. show that each of these terms has the dimension of energy per mass of fluid by.... a) converting each term to units of Btu/lbm beginning with pressure in psi, ..
Calculate the equilibrium conversion, then redo parts (a) through (c) to achieve a concentration that is 90% of the calculated equilibrium conversion.
From the magnetic moment of 1.7 μB per Co in metallic Co, predict what Ms will be. Note that a unit cell of Co contains 6 atoms, and has a volume of 6.68×10-2nm3.Ms (in kA/m):
Derive a Differential Equation which will show how temperature in the tank changes with time. State assumption used. Solve this model to obtain T(t) given that T(t=200s) = 50°C.
