In the gap between the two plates, the lubricant flows in one direction (x) by the pressure gradient. Lubricants are incompressible Newtonian fluids, flows are laminates, and terminal effects are ignored. Find the maximum flow rate [m/s] when the pressure difference (△P/L) per unit length is 25000 Pa/m. Data: clearance between plates (B) = 6 mm, lubricant viscosity (μ) = 25 cP (1cP = 10-3 Pa·s), lubricant density (=) = 0.88 g/cm3 Please.. explain more easy

Engine oil at 40 C [density 876 kg/m^3, viscosity 0.2177 kg/m.s] flows in a 22-cm-diameter pipe at a velocity of 1.1 m/s. The pressure drop (in Pa) of oil for a pipe length of 24 m is ?

From Table A.3, the density of glycerin at standard conditionsis about 1260 kg/m3 . At a very high pressure of 8000 lb/in2 , itsdensity increases to approximately 1275 kg/m3 . Use this datato estimate the speed of sound of glycerin, in ft/s.

The kinematic viscosity of and specific gravity of a liquid are 3.5 x 10-4 m^2 /s and 0.79, respectively. What is the dynamic viscosity of the liquid in N-s/m^2?

Engine oil at 40 C [density 876 kg/m^3, viscosity 0.2177 kg/m.s] flows in a 20-cm-diameter pipe at a velocity of 0.9 m/s. The pressure drop (in Pa) of oil for a pipe length of 20 m is

A thin layer of spherical particles rests on the bottom of a horizontal tube as shown in the figure below. When an incompressible fluid flows through the tube, it is observed that at some critical velocity the particles will rise and be transported along the tube. A model is to be used to determine this critical velocity. Assume the critical velocity, V, to be a function of the pipe diameter, D, particle diameter, d, the fluid density, p, and viscosity, μ, the density of the particles, Pp, and the acceleration of gravity, g. For a length scale of Dm/D=1/2 and a fluid density scale of Pm/p=1/0.9, what will be the critical velocity scale V/V (assuming all similarity requirements are satisfied)? Vm/V= i

An incompressible fluid oscillates harmonically (V = Vosinut, where Vis the velocity) with a frequency of 9 rad/s in a 6-in.-diameter pipe. A 1/5 scale model is to be used to determine the pressure difference per unit length, Ap, (at any instant) along the pipe. Assume that Api= f(D, Vo, w, t, u, p) where D is the pipe diameter, w the frequency, t the time, the u fluid viscosity, and p the fluid density. If the same fluid is used in the model and the prototype, at what frequency should the model operate? Wm i rad/s
