3.3.1. GATE 2005 Civil Engineering Problem

Try these first

1. 1.

   Define control volume in your own words.

   Hint

   Think about a box where fluid flows in and out.

2. 2.

   What is steady flow?

   Hint

   Does the water’s speed change in steady flow?

3. 3.

   What is a control volume?

   • A specific location
   • A defined area for fluid analysis
   • An equation

   Hint

   Think about where the water flows.

4. 4.

   True or False: In steady flow, velocity can change over time.

   • True
   • False

   Hint

   Does steady mean fluctuating or stable?

5. 5.

   A tank is filled with water, and a jet is projected outward at an angle. Calculate the resultant force exerted on the tank's wall if the jet velocity is 6m/s and the cross-sectional area is 0.1m².

   Hint

   Remember to apply the basic formula for momentum flux.

6. 6.

   Explain how varying jet angles affect the force recorded by a deflector when provided with specific axis details.

   Hint

   What can you deduce about components when angles change?
