19.2.1. Application of Bernoulli's and Momentum Equations

Try these first

1. 1.

   Define Bernoulli’s equation.

   Hint

   Think about how pressure, elevation, and velocity interact.

2. 2.

   What is a Reynolds number?

   Hint

   It's critical in determining laminar vs turbulent flow.

3. 3.

   What does Bernoulli's Equation primarily relate?

   • Pressure
   • Volume
   • Temperature
   • Pressure
   • Velocity
   • Elevation
   • Density
   • Pressure
   • Flow Rate

   Hint

   Think of the conservation of energy.

4. 4.

   True or False: A Reynolds number below 4000 always indicates laminar flow.

   • True
   • False

   Hint

   Recall the threshold values discussed.

5. 5.

   Design a simple water supply system. Calculate the total pressure drop for a system with a known pipe length, diameter, and minor fittings involved.

   Hint

   Make sure to include all pipe fittings and transitions!

6. 6.

   A fluid with a Reynolds number of 3500 flows through a pipe with a roughness ratio of 0.02. Using Moody’s chart, determine the friction factor and calculate the energy loss over a 100 m pipe.

   Hint

   Check the transition behavior between laminar and turbulent flows!
