Accurately determine the flow rate through various Parshall flume sizes with our easy-to-use online calculator. Essential for environmental engineering, irrigation, and wastewater treatment, this tool helps you compute open channel discharge based on measured head, ensuring precise water management.
Formula:
The Parshall Flume flow rate (Q) is calculated using empirical formulas based on the flume's throat width (W) and the upstream head (Ha). The general form is Q = C ⋅ Han, where C and n are coefficients specific to the flume size. These coefficients vary significantly by flume width.
