Ahydraulic turbine that generates 10mw of power is tested with the of a 1: 8 model, which operates at the same angular velocity as the prototype. assume that the efficiencies of both the model and the prototype are the same 1. calculate the power of the prototype 2. find load ratio (hp / hm) 3. find the flow relation (qp/ qm)

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.
