On Xilinx, design a logic circuit to implement the four functions, F1 – F4 described below, simultaneously using one `157 IC. F1 = a’b, F2 = a + b’, F3 = a xnor b, F4 = b’

Please explain the process from the start to the end where you get your result.

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.
