Avessel contains a gaseous mixture of a composition by volume 70% h2 and 30% co. it is desired that the mixture should be made in the proportion of 50% h2 and 50% co by removing some of the mixtures and adding some co. calculate per kmol of mixture to be removed and the mass of co to be added. the pressure and temperature in the vessel remain constant during the process.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)

A5 kg block of fe is dropped into a very large vat of water. the fe and water initial temperatures are 95 and 25 c, respectively. the fe final temperature is 25 c and the water can be treated as a thermal reservoir,. treated as a thermal reservoir take the water to be the system and determine the entropy generation. report vour answer in kj/k.
