Question -8 The petrol used for petrol engine contain, 84% carbon and 16% hydrogen. The air supplied is 80 % of that theoretically required for complete combustion. Assuming that all hydrogen is burnt, and that carbon burns partly to CO and partly to CO2 without any free carbon , find the volumetric analysis of dry exhaust gas.
Derive an expression for Concentration of substrate versus the length of the packed bed reactor as a function - determine the Vm" (mol/m2s) value necessary to convert 80% of the substrate to product in the reactor.
A process modification has been devised that will increase the yield to 75%. The additional investment required is $1,250,000, and the additional operating costs are negligible. Is the modification worth making?
From among the following, choose one which is not an exothermic process. 1. Ammonia synthesis 2. Methanol synthesis
Sphere A is moving at a speed Vo=16 ft/s when it strikes sphere B which is at rest and the impact causes sphere B to break into two pieces, each of mass m/2 Knowing that 0.7s after the collision one piece reaches point C and 0.9s after the collisi..

Name the microstructural products of eutectoid iron-carbon alloy (0.76 wt% C) specimens that are first completely transformed to austenite, then cooled to room temperature at the following rates:
Give the approximate minimum temperature at which it is possible to austenitize each of the following iron-carbon alloys during a normalizing heat treatment:
Explain the term "Selectivity" and "Yield".Selectivity is defined as the ratio of moles of desired product to moles of undesired product.Yield is defined as the ratio of moles of product formed to moles of reactant eitherfed or consumed and What a..
