Answer / parul

Flue gas analysis and a flue gas analyser enable you to
measure the concentrations of the pollutants present and to
adjust your burners for optimal combustion.
n exhaust-gas analyzer, particularly for emissions testing
of motor-vehicle engines has a sampling tube into which a
mixture of exhaust gas and ambient air is fed through gas
lines. A gas feed pump is disposed downstream of the
sampling tube with a flowmeter inserted in the air line
feeding electrical signals to a computing unit. The unit
computes instantaneous standard total flow rate, allowing
for gas pressure and temperature

i'm a chemical engineer with an aggregate of 80% and i'm going to attend for TCS next week...if i encounter a question like this how i have to answer... WHY YOU CHOOSE SOFTWARE RATHER THAN YOUR CORE COMPANIES?

BIOCHEMICAL ENGINEERING INSTRUMENTATION - EXAMPLE 29.4 : The resolution of separation, Rs for chromatography is given by the formula Rs = (difference in retention time) / (average width at the base). In a chromatogram, 3 peaks a, b and c are found. Average widths W at the bases of the solutes are : Wa = 20 s, Wb = 40 s, Wc = 30 s. Resolutions of separation, Rs for solutes b and c in comparison to a are 2 and 4 respectively. The differences in retention times T for b and c in comparison to a are (Tb - Ta) and (Tc - Ta), Ta = Tc - Tb : (a) Form 2 equations involving Rs as a function of Wa, Wb, Wc, Ta, Tb and Tc. (b) Find the values of Ta, Tb and Tc.

CHEMICAL ENERGY BALANCE - EXAMPLE 11.2 : Calculate the cooling duty, H required to condense and cool acetone from 100 degree Celsius to 25 degree Celsius at atmospheric pressure. The heat of vaporization for acetone at its normal boiling point is 30.2 kJ / mol. The boiling point of acetone at atmospheric pressure is 56 degree Celsius. The flowrate of acetone through the condenser is 100 mol / s = N. Value of sensible heat needed to increase the temperature of acetone in liquid form from 25 to 56 degree Celsius is 4.06 kJ / mol. Value of sensible heat needed to increase the temperature of acetone in vapor form from 56 to 100 degree Celsius is 3.82 kJ / mol. Unit of H is kJ / s.
