Challenge Problems
Push your limits with challenges.
Question 1
In a cylindrical tank, the inflow is 50 liters/min and the outflow is 40 liters/min. Calculate the change in fluid storage over one hour.
💡 Hint: Remember to calculate how much is entering versus leaving.
Question 2
Assuming a velocity profile across a pipe, how would you estimate the volumetric flow rate if the average velocity is 2 m/s and the pipe diameter is 0.1 m?
💡 Hint: Use J to calculate area based on diameter!
