using a 3 inch diameter conduit a 90 degree stub up with a 30 inch radius with a 48 inch and inch leg. Find the developed length thergain the overall length and the amount of 6 degree segment the 90 degrees to make the up

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.
