Q4 A plate 0.05 mm distant from a fixed plate moves at 1.2 m/s and requires a force of 2.2 N/m to maintain this speed. Find the viscosity of the fluid between the plates.

(Just Question a.) A water filled pipe has water flowing at v1= 5.90 m/s in a section of pipe where the diameter is d1= 20.2 cm and the pressure is known to be P1= 7.00×104 N/m2 above atmospheric pressure.     If the pipe carries the water 3.5 meters up hill without any change in diameter, what is the new absolute pressure within the pipe? After flowing up the hill described above, the pipe narrows to 80% of its original radius, what will be the new water velocity (v2) in the pipe? What will be the absolute pressure (P3) in the smaller pipe?   a. What is the volume flow rate through the smaller pipe?

A plate 0.05mm distance from a fixed plate moves at 1.25 m/s and required a force per unit area of 3 Pa to maintain this speed by using an oil of specific gravity 0.65. Find the dynamic viscosity in centipoise and kinematic viscosity in stokes of the fluid between the plates. Calculate the specific weight in kN/m³, density, and the specific gravity of a liquid having a volume of 662900 cm and weight of 55 kN

I am working on practice problems and am stuck on this question.

A cylindrical machine part moves within a surrounding cylinder. The centrelines of the part and the surrounding cylinder are coincident. The cylinder is full of an oil (viscosity 0.25kg/ms) that is not flowing i.e. no pressure gradient is applied. What is the value of the viscous force exerted on the machine part as it moves along the cylinder at a speed of 9m/s? • The machine part is 0.06m long and has a radius of 0.041m. • The ratio of the machine part radius to the cylinder radius is 0.98. • Assume that the flow is dominated by viscous forces. • Give your answer as an absolute value i.e. no negative sign, in Newtons to one decimal place.

I would really appreciate it if you could tell me how to solve the problem.
