 A fluid is filled between two parallel plates separated by a

A fluid is filled between two parallel plates separated by a distance of L. The top plate (z = L) is maintained at T and moving at a constant velocity of U; the bottom plate (z = 0) is maintained at T. and is stationary. If the flow is laminar and T> To, which one of the following statements regarding to the temperature profile in the fluid is true? (a) Linear with the max. temperature equal to TL (b) Parabolic with the max. temperature = TL, (C) Parabolic with the max. temperature >Tat the mid-plane (z = 0.5 L), 2 (d) Parabolic with the max. temperature > at the location (2), both of which increase with increasing U, (e) Parabolic with the max. temperature >T, at the location (z); both of which decrease with increasing U.
