Question

What does ?p = QR mean in words?

Viscous fluid will only flow through a pipe if the resistance is zero.

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 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.

If there is no pressure difference across a pipe, the flow is 1/R.

Viscous fluid will only flow through a pipe if the resistance is zero.

Explanation / Answer

delta P is the change of presuure

Q is flow rate

and R is resistance

if a viscous fluid is pushed thorugh the pipe, it will always flow from the region of High to low pressure

so

Pushing a viscous fluid through a pipe requires a drop in pressure along the direction in which the fluid is flowing through the pipe.

and

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.

are equally correct
