Challenge Problems
Push your limits with challenges.
Question 1
If a fluid has a density of 1000 kg/m³ and is 10 meters deep in a tank, calculate the pressure at the bottom of the tank assuming atmospheric pressure is 101325 Pa.
💡 Hint: Use hydrostatic pressure equation, remember to include atmospheric pressure.
Question 2
In a control volume where the pressure is given as a function of height, derive the expression for pressure gradient based on gravitational forces acting on the fluid.
💡 Hint: Consider the effects of height variations on pressure.
