3.2. Constant density

Try these first

1. 1.

   Define Bernoulli's Equation.

   Hint

   Think about energy types involved.

2. 2.

   What does the term 'constant density' refer to?

   Hint

   Consider fluids like water at normal conditions.

3. 3.

   What is the primary assumption of Bernoulli's equation?

   • Steady flow
   • Compressible flow
   • Viscous flow

   Hint

   Reflect on the flow features.

4. 4.

   Bernoulli’s equation is applicable in which of the following scenarios?

   • True
   • False

   Hint

   Consider the conditions for ideal fluid flow.

5. 5.

   A water tank has a hole at a depth of 10 meters. Calculate the speed of water as it exits. Assume atmospheric conditions.

   Hint

   Know the formula for velocity due to gravitational potential energy.

6. 6.

   Design a system using Bernoulli's principle to measure the flow rate of water in a pipe. Explain your choices for diameters and pressure readings.

   Hint

   Visualize the flow areas and how they relate to pressure changes.
