An insoluble wet granular material of 0.3m x 0.2m with 22mm thick is hold vertically. heat transfe from an air stream flowing perpendicular to the surface at a velocity of 5ft/s. the air stream has a wet bulb temperature of 29.6 c and dry bulb temperature of 50 c. the critical free moisture content os 0.03kg h2o/kg dry solid. the drying of this wet granular material is carried out in constant-free region.

What effect might melting sea ice have for people who live in coastal areas?

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
