Answer / engr. muhammad omer farooqi

End products of complete combustion are always carbon dioxide (CO2) and water (H2O). However incomplete combustion may lead to carbon monoxide (CO). Also this is true for 100% pure fuel which is not the case since every hydrocarbon has got some impurity which also shows itself in final products.

Answer / lafangey

along with poisonous gases,water also forms.....coz any fuel(hyrdrocarbon) has H in its molecules so it reacts with O2 and form water.

Carbon di oxide is major compound exhausted but some other
like carbon mono oxide and even small particales if present
in fuel may tends to suspended in air.The other major
compounds are nitrogen sulfur but all these creates the
pollution so now a days many precautions at=re taken into
account before manufacturing these types of fuels and well
pre treated before the final separation.

BIOPROCESS ENGINEERING - EXAMPLE 14.1 : In differential centrifugation of cells with diameter D in centimeter, the square of D is given by D x D = [18n ln (RF / RI) ] / [ (RP - RFF) Wt ] where n is the fluid viscosity (poise), RF is the final radius of rotation (cm), RI is the initial radius of rotation (cm), RP is cell density (g / ml), RFF is the fluid density (g/ml), W the square for the rotational velocity in (radians / s) (radians / s), t is the time required to sediment from RI to RF (s). Derive an equation for W as a function for D, n, RF, RI, RP, RFF and t, with the stated units above, in radian & degree.

PROCESS DESIGN - EXAMPLE 21.3 : According to a heuristic of chemical engineering plant design, assume a pressure difference dP = 4 psi for each 10-ft rise in elevation. A pump is needed to pump liquid from a storage tank at a lower elevation to a heating tank at a higher elevation with the elevation difference of 60 ft. (a) Find the pressure loss due to such elevation. (b) If the required minimum inlet pressure to the heating tank is 9 psi, with 1 control valve is installed between pump and heating tank, what is the dP minimum required for the control valve and the entrance to the heating tank when the heuristic mentions that at least 10 psi is required for the control valve? (c) The pressure at the inlet of the pump is 8 psi and the flowrate of the liquid produces pressure head of 50 psi. What is the total pressure produced by the pump? (d) Assume a pipeline dP of 2 psi / 100 ft for liquid flow in a pipe according to heuristic, what is the approximate maximum length of the pipe in ft that can be installed between the pump and the heating tank?
