What does Δp = QR mean in words? Pushing a viscous fluid through a pipe requires a drop in pressure along the direction in which the fluid is flowing through the pipe. If there is no pressure difference across a pipe, the flow is 1/R. If you increase the flow of a viscous fluid, you increase the pressure at the end of the pipe toward which the fluid if flowing. A viscous fluid will always move more and more quickly...

How

A viscous fluid is flowing through two different horizontal pipes. The pressure difference Δp between the ends of each pipe is the same. The pipes have the same radius but different length as shown. The relation between the flow rate through the pipes is B) QA-QB 2L

An experimental apparatus delivers a viscous fluid through a capillary tube 10 cm long with a bore diameter of 1 mm. The tube is broken, but tubing of bore diameter 2 mm is all that is available. What should be the length of the new tube in cm so that the experiment is otherwise unchanged, i.e., so that the volume flow rate remains as before?

Consider steady laminar viscous fluid between two parallel plates with distance h separated from each other. A pressure gradient dp/dx drives the flow. By considering forces acting on a small volume between the parallel plates, obtain the velocity profile, the volumetric flow rate, and the average velocity in terms of centerline velocity Umax Umax
The average velocity < v > of a viscous fluid through a pipe is proportional to...
The average velocity < v > of a viscous fluid through a pipe is proportional to the drop in pressure ∆P, length L, radius of the pipe r, and viscosity of the fluid η (units: kg/m/s). Performing various experiments it has been determined that the velocity is directly proportional to the drop in pressure divided by the length. Determine the dependence of < v > on these quantities.

1. As seenfrom figure, there is a laminar and viscous fluid flow betweentwo parallel plates where the one is moving with velocity y, other one is stationary. There exists pressure gradient in x direction. The bottom stationary plate is a porous plate andfluid is injected into the channel with V velocity. If theflow is steady, fully developed and incompressible flow, derive the velocity profile. Uo Vo

A particle moves falling vertically through a viscous liquid. The velocity is recorded as a function of time and it is observed that it corresponds approximately to the following function: v (t) = 10 (1 - exp (-t)), t in seconds v in m / s. a) Graph velocity versus time. Describe what happens in words. b) Calculate the instantaneous acceleration of the particle and subtract from it the acceleration of gravity (10 m / s²). Graph the resulting acceleration,...

Sulphuric acid is flowing through a 2.5 inch diameter and 50ft long pipe with a velocity of 0.006 m3 /s. The sulphuric acid has a viscosity of 25 mN.s/m2 and density of 1680 kg/m3 while the roughness of the pipe surface is 1.3 mm. If the operating temperature is 290K, determine fluid flow (examples turbulent, laminar or others).

3. Water flowing through a pipe assumes a laminar-flow velocity profile at some section is parabolic: u(0) -4J Figure 2 where u(r) is the velocity at any position r, ß is a constant,-11s the viscosity of water, and r is the radial distance from the pipe centerline. (a) Develop an equation for u(r) assuming a parabolic velocity profile and using the known velocities at the walls u(ro)-0 and the center u(0) (Just use symbols). (b) Develop an equation for shear...
