Question: If the viscosity of a liquid is doubled, what happens to the flow rate through a pipe, assuming all other factors remain constant?

Options:

Correct Answer: Flow rate halves

Solution:

According to Poiseuille\'s law, if viscosity is doubled, the flow rate will be halved, assuming other factors remain constant.

If the viscosity of a liquid is doubled, what happens to the flow rate through a pipe, assuming all other factors remain constant?

Correct Answer: Flow rate will be halved.

Step 1: Understand what viscosity is. Viscosity is a measure of how thick or sticky a liquid is.
Step 2: Know that flow rate is how fast the liquid moves through a pipe.
Step 3: Remember Poiseuille's law, which relates viscosity, flow rate, and other factors in a pipe.
Step 4: According to Poiseuille's law, if the viscosity of the liquid is doubled, the flow rate will decrease.
Step 5: Specifically, if viscosity is doubled, the flow rate will be halved, meaning it will flow slower.

Viscosity and Flow Rate – The relationship between viscosity and flow rate in a fluid, particularly as described by Poiseuille's law.
Poiseuille's Law – A principle that relates the flow rate of a fluid through a pipe to its viscosity, pipe length, pipe radius, and pressure difference.
