1.3. General Equation for Pressure Drop

Try these first

1. 1.

   Define pressure drop in your own words.

   Hint

   Think about fluid flow and resistance.

2. 2.

   What are the two types of losses in pipes mentioned in the section?

   Hint

   Consider what kind of factors lead to energy loss.

3. 3.

   What does the Darcy-Weisbach equation calculate?

   • Total flow rate
   • Pressure drop
   • Viscosity

   Hint

   Remember what ΔP stands for.

4. 4.

   True or False: Minor losses only occur due to friction in the pipe.

   • True
   • False

   Hint

   Consider factors other than pipe length.

5. 5.

   A pipe has a length of 200 meters, diameter of 0.05 m, and fluid flowing through it has a velocity of 2 m/s. Calculate the pressure drop using a friction factor of 0.03.

   Hint

   Make sure to substitute all values correctly into the equation.

6. 6.

   Propose a design for a piping system that minimizes friction losses while maintaining flow rate. What considerations should you factor in?

   Hint

   Think about what affects flow characteristics in the system.
