Example: L=10.0 m 2Y = 0.5 cm ad here An incompressible viscous fluid flows between two horizontal parallel plates as shown. The plates are spaced 0.5 cm apart and are very wide perpendicular to page. Flow is laminar and velocity profile at any cross section is given by, P 1000 Pa P = 0 Pa u =- p = 850 kg/m Y (AP **[0] 2L where AP is the pressure change that occurs in length L. Calculate average mechanical energy loss h, between the pressure gages. Then show that mechanical energy loss also satisfies the equations 2 SH gh = cv y and gh = Re m =RO () () where Re= = PVY
