Question
What does P = QR mean in words?
Question 5 options:
If there is no pressure difference across a pipe, the flow is 1/R.
A viscous fluid will always move more and more quickly through a pipe because the pressure increases.
Pushing a viscous fluid through a pipe means a drop in pressure.
Viscous fluid will only flow through a pipe if the resistance is zero.
If you increase the flow of a viscous fluid, you increase the pressure at the end of the pipe.
If there is no pressure difference across a pipe, the flow is 1/R.

Explanation / Answer
?P: Pressure difference across pipe.
So, if a viscous fluid is pushed into the pipe where resistance(R) value and flow rate(Q) is given, then it will always flow from high to low pressure.
Hense, option C is correct.
If flow rate will be changed then, R also might get changed and would compansate the value.
