Challenge Problems
Push your limits with challenges.
Question 1
A horizontal water jet with a velocity of 12 m/s and a diameter of 20 mm strikes a vertical plate. Calculate the force exerted on the plate assuming ρ = 1000 kg/m3.
💡 Hint: Use the formula F = ρ * Q * V, where Q is the volumetric flow rate.
Question 2
A sluice gate opens to let water flow. If the upper water level is 8m and the lower is 2m with a velocity of 4m/s, calculate the resultant pressure force acting on the gate.
💡 Hint: Consider the average pressure due to the height difference.
