Pump is moving 475gpm of water at 75ºF from an open reservoir 4feet below the elevation of the pump. The inlet to the pump is located 2 feet below the surface of the water and 8feet from the pump entrance, horizontally. The inlet pipe is 4-inchgalvanizediron pipe that has an abrupt entrance (C = 0.5) and one90º elbows(C = 0.9). How muchnet positive suction pressure is available at the pump in

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

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.
