g Further assume that, when transition happens, it takes place over a negligible distance in the x-direction. Calculate the momentum thickness at the trailing edge in each of these cases: (a) laminar flow over the entire plate; (b) turbulent flow over the entire plate; (c) transition forced (for example, by roughness) at x

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.
