An infinite plate is moved over a second plate on a layer of liquid . for small gap width d we assume a linear velocity distribution of the liquid . the liquid velocity is 0.65 centipoise and its specific gravity is 0.88. determine 1.kinematic viscosity
2.shear stresses on upper and lower plates
3. the direction of each share calculated above

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
