4 cards from this section. Quick, good the night before a test.
What does Q represent in the discharge equation?
Think of it as the amount of water flowing per second.
What is the main purpose of using rectangular notches?
Consider how we might measure rivers or irrigation systems.
What is the main equation for calculating discharge over a rectangular notch?
Remember the power of H in the equation.
True or False: The discharge coefficient (Cd) is always equal to 1.
Consider how conditions might alter the coefficient.
Calculate the discharge for a rectangular notch with a width of 1 meter and a head of 2 meters using Cd = 0.65. Include the calculation steps.
Start by calculating the square root and powers before multiplying.
Create a hypothetical scenario where the head varies seasonally. Discuss the implication on flow measurement accuracy using rectangular notches.
Consider the implications of fluctuating water levels.
