A lubricant oil with a density of 897 kg/m and viscosity of 0,4 kg/ms is flowing upward between two vertical parallel plates as is shown in
the figure. The flow between the plates is known as incompressible, steady, uniform and fully-developed laminar. One of the plate at the
right-hand side is pulling up with a constant velocity of U=3,1 m/s. The gap between the plates is H=1 cm. The length and the width of the
plates are L=382 cm and w=100 cm, respectively. For this flow generation, find:
a) the magnitude of the local velocity at the middle of gap between two plates (in m/s). (Please use 2 decimal digits.)
b) the generated flow rate (in m /s). (Please use 4 decimal digits.)
c) the magnitude of the shear stress on the moving plate (in Pa). (Please use only 1 decimal digit.)
Please solve this question step by step to reach correct answers.
correct answers:
a) 1,28
b) 0,0137
c) 168,0
