1.1. Basics of fluid mechanics-I(Cont.)

Try these first

1. 1.

   What is the formula to calculate buoyant force?

   Hint

   Think about what happens when an object displaces water.

2. 2.

   What does pressure do as you go deeper in a fluid?

   Hint

   Consider the weight of the water column above you.

3. 3.

   What principle explains why objects float or sink in a fluid?

   • Archimedes' Principle
   • Bernoulli's Principle
   • Pascal's Principle

   Hint

   Think of a classic wooden boat!

4. 4.

   The deeper you go in a fluid, pressure...

   • Increases
   • Decreases

   Hint

   Imagine the pressure on your feet when swimming deep!

5. 5.

   A circular gate with a diameter of 2m is submerged to a depth of 5 meters in water. Calculate the resultant force acting on the gate.

   Hint

   Convert diameter to radius before using the area formula.

6. 6.

   An object with a volume of 1m³ and density of 2000 kg/m³ is submerged in water. Calculate the buoyant force acting on it.

   Hint

   Remember to use gravity's standard value.
