A handy and practical tool for easy of caculating nozzle pressures and friction loss is fire hose. Slide rule method. Rugged construction and coated. It will never get wet and look like new after years of use.
Side A: Shows nozzle pressure calculations. Great for calculating nozzle pressure vs. flow rates.
Side B: Shows friction loss calculations. Great for calculating friction loss in diffierent diameters of fire hose
