Area = 0.349 ft 2. g h = Θ A (x s - x) where Updated with 2020-21 charges. Please enter data for Tank Radius (radius is 1/2 of diameter) and side water depth. StormChamber is a stormwater systems solution that functions in all environments. Rectangular Tank. What our customers say. You need to fill in the radius. The amount of evaporated water can be expressed as: g s = Θ A (x s - x) / 3600 (1) or . Evaporation of water from a water surface - like an open tank, a swimming pool or similar - depends on water temperature, air temperature, air humidity and air velocity above the water surface. Online calculators and formulas for a surface area and other geometry problems. 1, 2. Rain Water Catchment Calculator How much rainwater can you harvest? Select both the Contour Lines length (ft) and the Watershed area (acr) to calculate. Therefore: V(tank) = π r 2 l Calculate the filled volume of a horizontal cylinder tank by first finding the area, A, of a circular segment and multiplying it by the length, l. This calculator is designed to supply the area of any potential collection surface of any length and width in square feet and/or square inches, based on the length and width values entered in feet and inches, and the potential and estimated actual rainwater recovery in gallons. Watershed lag time equation calculator solving for watershed lag time given watershed hydraulic length, potential watershed storage and average watershed slope ... watershed area: linear profile slope: References - Books: Martin Wanielista, Robert Kersten and Ron Eaglin. A is the total watershed area in acres; and 3630 is a conversion factor of to convert the final result to cubic feet. 2. Draw a rectangle on the pond shape that would approximate the area of the pond if some water was eliminated and placed onto an equal amount of land. Need help selecting which tank is right for you? Make sure to use the actual water depth in your calculations, not the depth of the container.
