1.6. Pressure Drop Parameters

Try these first

1. 1.

   What is a pressure drop?

   Hint

   Think of what happens to water when it flows through a narrow opening.

2. 2.

   Name a factor that affects pressure drop.

   Hint

   Consider how wide or narrow a pipe is.

3. 3.

   What key factors affect pressure drop in a pipe?

   • Diameter
   • Density
   • Viscosity
   • Flow Velocity
   • Temperature
   • Density
   • Pressure
   • Only Density and Viscosity

   Hint

   Recall the elements discussed in class.

4. 4.

   True or False: Dimensional analysis simplifies the number of required experiments.

   • True
   • False

   Hint

   Think about the purpose of dimensional analysis.

5. 5.

   Design an experiment that analyzes how changing the fluid in a pipe (from water to a glycerin solution) affects pressure drop. Explain your approach.

   Hint

   Consider how viscosity plays a role in fluid behavior.

6. 6.

   Using Buckingham Pi theorem, develop dimensionless groups for the relationship between pressure drop and the aforementioned factors. Explain your reasoning.

   Hint

   Recall the number of variables and reference dimensions required.
