Questions & Step-by-Step Solutions

If the viscosity of a liquid is doubled, how does it affect the flow rate through a pipe?
  • 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.
  • 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 dimensions, and pressure difference.
