A half body is formed by the superposition of a uniform flow and a source. Consider the superposition of a uniform flow with a velocity of 300 ft/s and a source placed at the origin with a strength of 100 ft2/s. What is the gage pressure at a point located at θ=80o, r = 0.3 ft? The pressure upstream is the atmospheric pressure and the density of the fluid is rho=0.00235 slug/ft3.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

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.
