A pipe difference cross sections (2.2, 25.8, 6.5) cm^2 respect at points (1, 2, 3) the height of these points 92, 65, 21 cm based to the reference line. The pipe join to an open tank height of the water in the tank is 2 m base to the reference line. Calculate: i/ Q? ii/P & V at all points? Ans. (Q=3.84*10^-3 m^3/sec)

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.
