Question 1
A water jet is directed at a surface at a 30-degree angle. Calculate the force exerted on the surface if the jet has a momentum flow rate of 100 kg/s.
💡 Hint: Consider how angles affect vector components.
Question 2
Analyze the momentum change in a control volume with an inlet velocity of 5 m/s and an outlet velocity of 3 m/s. Assume a density of 1,000 kg/m³.
💡 Hint: Remember to factor in the densities when calculating momentum.
