yes it is hard questoin that is why I am looking for help

Engine oil at T= 60°C is forced to flow between two very large, stationary, parallel flat plates separated by a thin gap
height h = 3 mm. The plate dimensions are L= 800 mm and W= 300 mm. The inlet pressure is 130 kPa, and outlet
vents to the atmosphere. As h/L is small, assume velocity changes with respect to x are negligible. From the equations
of motion, generate the expression for u(v).
Pot
Also, estimate the volume flow rate of oil. Recall the volume flow rate is
Pin
the integral of the velocity over a cross-sectional area normal to the flow.
Finally, calculate the Reynolds number of the oil flow and state if the
flow is laminar or turbulent. Use the gap height h as the characteristic
length and average velocity as the characteristic speed. For flow between
flat plates, the critical Reynolds number, Reer is 1400.
