With a reservoir pressure of 1.0 MPa and temperature of 750 K, air enters a converging-diverging nozzle, in a steady fashion. Flow is isentropic and k=1.4. If exit Mach number is 2 and throat area is 20 cm2 , find (a) the throat conditions (static pressure, temperature, density, and mach number), (b) the exit plane conditions i

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.
