Answer / mm

Id fan maintains the pressure equillibrium inside the
furnace by providing slightly negative pressure inside the
furnace, so that the gases are let out of the furnace to
the chimney. If the chimney height is more, it may not be
adequate to evacuate the gases in the furnace. Hence Id fan
acts as a booster to maintain draft in the furnace, though
some may be of the opinion that Id fan acts as a sucker of
the gases generated in the furnace thus avoiding explosive
gases to be let into the environment.

Answer / vinayak

It maintains the pressure equillibrium inside the
furnace so that the gases are let out of the furnace to
the chimney. And complete combustion of the fuel

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.9 : In the modelling of the total of n rolls of a dice by an engineering student, let D be the random outcome of rolling a dice once. (a) Find the probability of outcome of D = 1, 2, 3, 4, 5 and 6. (b) Find the average score of each rolling of a dice D. (c) Find the expected value, Sn of n rolls of a dice in term of n and D. A new dice has a value of D* = D - 3.5. (d) Find the values of D* for each volume of D = 1, 2, 3, 4, 5 and 6. (e) Find the equivalent model of Sn in term of n and D. (f) Find the expected value of D*.

Chemical Engineering Material Balance - Three hundred gallons of a mixture containing 75.0 wt % ethanol and 25 wt % water (mixture specific gravity = 0.877) and a quantity of a 40.0 wt % ethanol - 60 wt % water mixture (specific gravity = 0.952) are blended to produce a mixture containing 60.0 wt % ethanol. The specific gravity of a substance is the ratio of density of a substance compared to the density of water. The symbol of weight percent is wt %. (a) Estimate the specific gravity of the 60 % mixture by assuming that y = mx c where y is wt % ethanol, x is mixture specific gravity. Values for m and c are constants. (b) Determine the required volume of the 40 % mixture.
