Working successfully with hydraulic systems requires two things: Understanding the definitions of the basic factors involved in hydraulic calculations and seeing how those values relate to and influence each other in the real world. The last installment in this series of articles focused on the relationship between flow and velocity with respect to water. The related concept we’ll explore this time takes our understanding of that key relationship a step farther by exploring a specific pair of additional relations summarized by
As watershapes have become increasingly complex, the need for reliable hydraulic designs that maximize efficiency and reliability is now more pressing than it’s ever been, says hydraulics expert Steve Gutai. With this installment of his ongoing series on hydraulics, he launches a sequence of articles that will explore principles behind the fluid mechanics and hydraulics of custom
Of all the concepts of hydraulic-system design, there are few that have more importance than the correlation between water flow (that is, capacity expressed as gallons per minute) and line velocity (the speed at which the water travels). As water travels through a pipe, its increase in speed (that is, its line velocity) results in an increase in resistance (expressed as feet of head) and in a reduction of end pressure, which is measured in pounds per square inch (psi). In other words, an increase in friction losses and a drop in pressure is the result of increased water velocity at a given flow. If that makes sense to you without further explanation, then you know much of what you need to know when it comes to selecting pipes and fittings and setting up a watershape's plumbing system. If it doesn't, this article will cover the basics - from selecting pipes and sizing lines to
Put yourself in your customer's swim suit for a moment: You're floating in a lounge chair in your pool, taking in the surroundings and proud ofwhat you and your family now enjoy. As you scan the perimeter of the pool, you spot something you're certain wasn't there the last time you looked. Yes, you're sure of it: A portion of the deck seems to be rising above the backside of the coping. Instead of continuing to enjoy a lazy afternoon's float, you now start to

As you scan the perimeter of the pool, you spot something you're certain wasn't there the last time you looked.
