A counter-flow absorption system recycles the liquid agent through an external system. The external system removes 97% of the pollutant from the liquid phase. What liquid/gas flow rate is needed to achieve a final emissions control of 90%? Your answer should be only a function of the Henry’s law constant, KH, and pressure, P.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
