Challenge Problems
Push your limits with challenges.
Question 1
A fluid flows around a cylindrical object. If the pressure gradient on one side of the cylinder is 500 Pa/m and on the opposite side is 300 Pa/m, calculate the expected net force acting on the fluid around the cylinder.
💡 Hint: Remember the basic principle: Force = Pressure x Area.
Question 2
In a complex machinery system, analyze how changes in stream functions would affect the overall energy efficiency of fluid movement.
💡 Hint: Consider how energy conservation applies with changing velocities.
