Question 1.
What is Bernoulli's equation used for?
Show hintHide hint
Think about energy conservation in fluids.
Question 2.
Define a streamline.
Show hintHide hint
Consider how water flows in a river.
3Question 3.
What is the Bernoulli's equation primarily used for?
- Predict fluid velocity
- Calculate temperature changes
- Estimate density variation
Show hintHide hint
Consider what parts of flow are being analyzed.
4Question 4.
True or False: Friction is negligible when applying Bernoulli's equation.
- True
- False
Show hintHide hint
Think back about flow conditions!
Question 5.
A water tank is 5m high, and water is flowing out from a nozzle at the bottom. Using Bernoulli’s equation, calculate the speed of the exiting water.
Show hintHide hint
Consider the potential energy converting to kinetic energy at the nozzle.
Question 6.
A pipe narrows from a diameter of 10 cm to 5 cm. Calculate the velocity increase using Bernoulli’s equation assuming no energy loss.
Show hintHide hint
Remember that flow rate must remain constant across the pipe's cross-sections.
