20.1.1. Gate Valve

Try these first

1. 1.

   What does a gate valve do?

   Hint

   Think of how a gate operates.

2. 2.

   What happens to the flow pattern when a gate valve is half-open?

   Hint

   Consider how water flows through obstacles.

3. 3.

   What is the primary function of a gate valve?

   • Control flow
   • Measure pressure
   • Increase pressure

   Hint

   Think about what a gate does!

4. 4.

   True or False: A fully open gate valve creates the highest level of turbulence.

   • True
   • False

   Hint

   Consider the characteristics of flow in an open passage.

5. 5.

   Design a piping system that includes a gate valve and a globe valve. Describe the ideal application for each and how energy loss would be minimized in the overall system.

   Hint

   Consider the specific fluid dynamics and application for each type of valve.

6. 6.

   Using Bernoulli's Equation, calculate the pressure loss when a fluid travels through a system with a partially opened gate valve. Assume given velocities and diameters for the initial calculations.

   Hint

   Identify initial and final conditions to set up Bernoulli’s equation accurately.
