Two parallel plates kept 205mm a part have laminar flow of oil. The lower plate is stationary and the upper plate is moving with 3.5m/s. find: a- velocity distribution formula. b- The value and position of the maximum velocity.c- The discharge per meter width. d- The shear stress at the plates. e- The difference in pressure between two points 55m apart. f- The velocity gradient at the plates. g- The velocity at 120mm. Assume viscosity of oil to be 24.5 poise. The velocity distribution in the boundary layer is given by :u/U=(y/d)^0.23 where u is the velocity at a distance y from the plate and u=U at y=d , 8 being boundary layer thickness. Find: a-The displacement thickness .b- the momentum thickness.c- the energy thickness. d- Boundary layer shape factor .e- energy loss due boundary layer if a particular section. The boundary layer thickness is 18mm and the free stream velocity is 11 m/s. if the discharge through the boundary layer region is 5m3/s per meter width, express this energy loss in term of meters of head. Take p=1.2 kg/m3. Your answer The velocity vector in a flow is given by :V=3xi-4yj-7zk Determine the stream equation passing through a point L(1,0,3) Your answer
