Pipe Friction Calculator
Why worry about friction?? Not taking into account friction losses when designing your waterfall or pond system could be costly 1) It can lead to an oversized pump 2) worst it can lead to a higher monthly electric bill. Our pond and waterfall calculators provide the correct size pipe to prevent friction losses. Or you can use the calculator below
Enter your pipe size, gph and total pipe run to make sure the pipe is not to small causing inefficiency which could lead to overspending on pump and power usage.
