Awaste gas stream containing 190 ppm by volume ) vinyl chloride is to be treated with activated carbon ina packed bed at a rate of 20 m3/min to reduce its concentration by 98%. using the above breakthrough data, determine the bed diameter, the height and pressure drop if an adsorption period of 10 h is allowed. the superficial gas velocity to be used is the same as that of the experimental study.

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
