One cycle of the power dissipated by a resistor (R = 700 Ω) is given by P(t) 55 W, 0 < t < 18.0 s P(t) = 35 W, 18.0 < t < 30 s This periodic signal repeats in both directions of time. What is the average power dissipated by the 700-Ω resistor? Pau to within three significant digits)

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.
