Challenge Problems

Push your limits with challenges.

Question 1

Applying Bernoulli's equation, calculate the pressure difference in a fluid flowing through a horizontal pipe that narrows from 10 cm to 5 cm with a flow rate of 40 liters per minute.

💡 Hint: Recognize the relationship between flow rates, cross-sectional areas, and subsequent velocities.

Question 2

Given a jet striking a plate at a 45-degree angle with a velocity of 15 m/s, calculate the forces acting on the plate if the mass flow rate is 2 kg/s.

💡 Hint: Break down velocity into components to effectively apply momentum principles.
