Challenge Problems
Push your limits with challenges.
Question 1
In a cylindrical tank, water exerts a normal stress at the base due to its weight. If the water column is 10m high and has an area of 2m², calculate the normal stress acting at the base. Use the density of water as 1000 kg/m³.
💡 Hint: Consider how density and height work together to determine pressure.
Question 2
Given a fluid flowing through a pipe where the velocity is halved at the outlet compared to the inlet and the input pressure is known, how would the momentum flux change?
💡 Hint: Think about how momentum is calculated in flowing fluids.
