Question 1

What is the main purpose of the Darcy Weisbach equation?

  • To calculate total pressure in a pipe
  • To compute head loss due to friction
  • To determine velocity of flow

💡 Hint: Think about what happens when fluid flows and encounters resistance.

Question 2

The loss coefficient at the entry of a pipe is generally considered to be?

  • True
  • False

💡 Hint: Remember the general values used for entry and exit.

Challenge Problems

Push your limits with challenges.

Question 1

Calculate the required horsepower for a pump in a system with conditions: head loss = 20m, diameter = 0.1m, length = 500m, friction factor = 0.02. Efficiency of the pump is 75%.

💡 Hint: Use the formula Power = Weight flow x Head loss / Efficiency.

Question 2

A water system experiences a Reynolds number of 60,000 and uses tubing with a roughness ratio. How would you interpret the friction factor from Moody's chart given this Reynolds number?

💡 Hint: Remember how turbulent flow behaves as compared to laminar flow.
