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 through a pipe because the pressure increases in the direction in which the fluid is flowing through the pipe.
Viscous fluid will only flow through a pipe if the resistance is zero.

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

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.

Using the principles of Poiseuille's law, which statement is false? Resistance offered by a tube is inversely proportional to its length. As the diameter of a tube decreases, the pressure gradient increases. The more viscous the fluid, the harder it is to move the liquid through a tube. Pressure required to achieve a given flow varies directly with the length of the tube.

Water can be considered as a non-viscous incompressible fluid of density p. A laboratory set-up is such that water flows through a pipe, exhibiting a laminar and steady-state flow. At the top end of the pipe, the flow tube has a cross-sectional area A and point 1 (located on the central streamline) is exposed to the ambient environment. The pipe drops through a A vertical distance h7 while its area decreases to when it reaches point 2 (also on the...
