So, you think you know a lot about water and wastewater hydraulics. Letās see how you do in the little test below. There are no passing grades or prizes, just the satisfaction of getting a few of these correct. Theyāre not easy.
The correct answers are at the bottom (but donāt peek).
Quiz time!
- What is the name of the equations for unsteady, non-uniform one-dimensional flow in open channels.
- What is the name of the curve that converts fixture units into peak flow rate for use in building plumbing?
- What does PVC stand for?
- Name the four pump characteristic curves.
- What dimensionless number describes the relative importance of inertial vs. viscous forces?[I told you these werenāt easy]
- Name an equation/diagram that converts roughness and Reynolds number into Darcy-Weisbach friction factor.
- What was the name of the first pipe network model that Haestad Methods/Bentley Systems developed, and whatās Bentleyās current top-of-the-line pipe network model?
- What is the equation for converting rainfall intensity into runoff for small areas?
- What happens when the actual pressure drops below the vapor pressure of water?
- What does āidfā stand for in rainfall-runoff modeling?
