19.9.2. Using Linear Momentum Equations

Try these first

1. 1.

   Define major losses in pipe systems.

   Hint

   Think about what affects the fluid's energy as it moves through the pipe.

2. 2.

   What is the Reynolds number?

   Hint

   Recall how it categorizes flow regimes.

3. 3.

   What primarily causes major losses in a pipe system?

   • Friction
   • Valves
   • Bends

   Hint

   Think of what slows down the fluid flow in the system.

4. 4.

   True or False: A Reynolds number below 2300 indicates turbulent flow.

   • True
   • False

   Hint

   Recall the flow classification based on Reynolds number.

5. 5.

   A water supply system has 500 meters of a smooth pipe with a diameter of 0.2 m and a flow rate of 0.1 m³/s. Calculate the Reynolds number, and categorize the flow.

   Hint

   Gather necessary properties of water to solve it.

6. 6.

   If the pressure at point A in a pipe is 200 kPa and at point B downstream is 150 kPa, calculate the energy loss due to friction assuming no other losses.

   Hint

   Apply fluid's hydrostatics to derive losses.
