Question 1
Calculate the average velocity in a flow with a known velocity field defined as u = 5 - y², across the area A = [-h, h]
💡 Hint: Remember to factor in the limits of integration.
Question 2
Using the given velocity field u = 3 - x², derive appropriate vorticity components at a point in the flow region.
💡 Hint: Identify which velocity component to differentiate based on the field's behavior.
