Q
Q: If the viscosity of a liquid is doubled, how does it affect the flow rate through a pipe?
Solution:
According to Poiseuille's law, if viscosity is doubled, the flow rate is halved, assuming all other factors remain constant.
Steps: 6
Show Steps
Step 1: Understand viscosity. Viscosity is a measure of how thick or sticky a liquid is.
Step 2: Know that flow rate is how fast a liquid moves through a pipe.
Step 3: Learn about Poiseuille's law, which states that flow rate depends on viscosity, pipe length, pipe radius, and pressure difference.
Step 4: Recognize that if viscosity increases (is doubled), it makes the liquid thicker.
Step 5: Realize that thicker liquids flow more slowly through pipes.
Step 6: Conclude that if viscosity is doubled, the flow rate will be halved, meaning the liquid will flow slower.
