Challenge Problems
Push your limits with challenges.
Question 1
You have a fluid flowing through a pipe that narrows from a diameter of 0.5 m to 0.25 m. Calculate the velocity if the inlet flow rate is 10 m³/s.
💡 Hint: Remember to convert diameters to radius for area calculations.
Question 2
Given a velocity distribution of u = x² - y² in a flow field, determine if the flow is rotational or irrotational by evaluating the angular velocities.
💡 Hint: Review angular velocity definitions for rotational flow.
