Question 1.
Define pressure in your own words.
Show hintHide hint
Think about how weight is distributed over a surface.
Question 2.
What is viscosity?
Show hintHide hint
Consider how honey flows compared to water.
3Question 3.
What is the formula for pressure?
- P = F/A
- P = A/F
- P = F*A
Show hintHide hint
Remember how force distributes over a surface.
4Question 4.
True or False: Viscosity describes how easily a fluid flows.
- True
- False
Show hintHide hint
Think about thick vs. thin fluids.
Question 5.
Design a comprehensive experiment to measure the pressure variation across different fluid densities and flow rates. Discuss the use of dimensionless parameters in reducing your experimental workload.
Show hintHide hint
Consider how different densities affect pressure and why that matters in design.
Question 6.
Given a scenario where a sphere is moving through a viscous fluid, calculate the drag force acting on it and how changing viscosity would affect this force. Use dimensionless analysis to support your conclusions.
Show hintHide hint
Think about how increasing viscosity would change flow patterns around the sphere.
