HIDE DRAIN COVER FLOW RATE GUIDE
Improve your design aesthetics with HIDE exterior drain cover solutions. Effortless elegance enhancing your hardscape.
Flow Rate Guide - Technical Explanation:
Disclaimer: The flow rate through a slot drain is influenced by the slot’s cross-sectional area and the hydraulic conditions, including the slope and roughness of the channel. In this estimation, we utilised standard flow rates for a known slot width and adjusted proportionally based on the given slot dimensions. For precise flow rate determination, it’s recommended to perform detailed hydraulic calculations that consider site-specific parameters or to consult with a drainage engineer.
The following Flow Rates are calculated and can be downloaded below:
- 214mm Square Drain Cover
