Water at 40°F is pumped from a lake at elevation 5173 ft to a snow-making machine at a rate of 120 gpm. The snow making machine is at elevation 5512 ft and requires the water to be at a pressure of 180 psi. The steel pipe (ε = 0.00015 ft) is 2000 ft long and 3 inches in diameter.
(a) Make a sketch to define the problem.
(b) Determine the head that the pump must add.

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.
