A pump at point A in a water delivery system produces 200 ft of head at a flow of 1000 gpm. It delivers water to a point B from a reservoir. If the head loss between point A and B is 20 feet, what is the pressure at point B in psi and kPa if B is at the same elevation as the water surface of the reservoir from which the pump is withdrawing water? (Ans: pB = 78.0 psi or 537.93 kPa)

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed. gi) ifn 1, what will happen to the material when transformed material when

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.
