Consider the factors influencing a problem.
3Question 3.
What does dimensional analysis help to simplify?
- Numerical computations

Question 5.
Using dimensional analysis, derive the relationship for the drag force on a sphere in a fluid, incorporating relevant variables such as diameter, fluid density, and velocity.
Show hintHide hint
Consider how the drag force relates to the fluid's characteristics.
Question 6.
Formulate a dimensional analysis problem for a scenario similar to concrete flow through a pump, specifying variables like pump diameter, concrete density, and viscosity.
Show hintHide hint
Think about how flow rate affects different properties under pressure.
