The specific volume of water vapor at 0.3 mpa, 160°c is 0.651 m/kg. if the water vapor occupies a volume of 1.9 m^3, determine the amount present, in kg.

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.

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point. the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
