Question 1.
What does Bernoulli's Equation state?
Show hintHide hint
Remember the formula includes pressure, velocity, and height.
Question 2.
What type of flow does Bernoulli's Equation apply to?
Show hintHide hint
Is the flow turbulent or calm?
3Question 3.
What does Bernoulli's Equation express in fluid flow?
- Conservation of mass
- Conservation of energy
- Conservation of momentum
Show hintHide hint
Consider what happens to energy in a flowing fluid.
4Question 4.
True or False: Bernoulli's principle can be applied to turbulent flow.
- True
- False
Show hintHide hint
Is turbulence a stabilizing factor?
Question 5.
A Venturimeter shows a pressure difference of 20 kPa between its two ends. Calculate the flow velocity when the diameter of the wider end is 100 mm and the narrower end is 50 mm.
Show hintHide hint
What principles connect pressure difference with velocity in a fluid?
Question 6.
Design an experiment to test Bernoulli's Equation using water flowing through different pipe diameters. Explain how you would measure pressure and flow rates.
Show hintHide hint
Consider how changes in pipe diameter will affect pressure and velocity.
