Practice Questions
Test your understanding with targeted questions
What is the Froude number for a flow with a velocity of 6 m/s at a depth of 0.5 m? (Use g = 9.81 m/s²)
💡 Hint: Remember, Froude number is a ratio of velocity to the square root of gravitational force times depth.
List two formulas used to calculate energy loss in hydraulic jumps.
💡 Hint: Energy loss can be calculated based on depth differences and flow velocities.

Challenge Problems
Push your limits with advanced challenges
In a rectangular channel, we have a water flow depth (y1) of 0.15 m with a velocity (V1) of 2.5 m/s. Calculate the Froude number, determine if a jump will occur, and find the sequent depth (y2) if Fr1 is greater than 1. Include energy loss calculations.
💡 Hint: Start with calculating the Froude number; it dictates subsequent calculations.
A reservoir discharges water into a channel where the initial Froude number is 4. Calculate the energy loss when the depth is 2 m before a jump occurs and identify risks associated with this discharge rate.
💡 Hint: Carefully analyze the hydraulic impact of elevated flow rates on structure integrity.
