1. Show the complete derivation needed for computing the thickness of fluid formed by overflowing oil-tank. If the mass flow rate (density x volumetric flow rate) is fixed and known, steady state behavior can be assumed, the oil spills over an inclined plane at an angle 0 and film thickness, d is much smaller than the width or the length of the inclined plane. To obtain all credit: (a) write all postulates, assumptions, boundary conditions, and equations as clearly as possible. (b) sketch the velocity profile, etc., obtained as a part of your solution procedure
