The velocity potential for a certain inviscid, incompressible flow field is given by the equation φ=8x2y-(23)y3 where φ has the units of m2/s when x and y are in meters. determine the pressure at the point x = 2.3 m, y = 2.3 m if the pressure at x = 1 m, y = 1 m is 1900 kpa. elevation changes can be neglected, and the fluid is water.

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.
