Challenge Problems
Push your limits with challenges.
Question 1
Consider a cylindrical tank with a piston compressing air. If the piston moves at a speed of 0.1 m/s, calculate how the density changes with time if initially, the density is known.
💡 Hint: Account for changes in the volume and apply the continuity equation.
Question 2
Given a two-dimensional flow field represented as v(x,y) = (x, y^2), determine if the flow is incompressible or not.
💡 Hint: Remember to differentiate with respect to each variable and sum them.
