Find More Calculator ☟ The Gutter Flow Rate Calculator is designed to help homeowners and builders determine the flow rate of water through a gutter system based on its dimensions and the intensity of rainfall. This is crucial for ensuring that gutters are appropriately sized to handle heavy rain and prevent overflow, which can cause water damage to buildings.Calculation FormulaThe formula used to calculate the flow rate is:\[\text{Flow Rate (gallons/minute)} = \text{Cross-sectional Area (sq ft)} \times \text{Rainfall Intensity (in/hr)} \times 448.831\]Where:Cross-sectional Area is calculated from the width and depth of the gutter (converted to square feet).Rainfall Intensity is the rate of rainfall in inches per hour.448.831 is the conversion factor from cubic feet per second to gallons per minute.Example CalculationIf your gutter width is 5 inches, depth is 4 inches, and rainfall intensity is 2 inches per hour:\[\text{Cross-sectional Area} = \frac{5 \times 4}{144} = 0.1389 \text{ square feet}\]\[\text{Flow Rate} = 0.1389 \times \frac{2}{12} \times 448.831 = 10.37 \text{ gallons/minute}\]This tool helps ensure your gutters can handle the expected rainfall, thereby protecting your property from potential water damage.Gutters Cost Calculator – Estimate Cost of Seamless Gutters
The Sheet Metal and Air Conditioning Contractors’ National Association addresses rain intensity and design area of a roof with this new tool.August 3, 2017The Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA) is an international trade association representing 3,500 contributing contractor firms. SMACNA notes that one of the most frequently asked architectural questions the association receives is about sizing gutters and downspouts. In response, SMACNA’s Technical Resources Department has created a free Downspout and Gutter Sizing Calculator.Now architects, engineers, designers, contractors, and facility managers can easily and accurately size downspouts and gutters according to the specifications in SMACNA’s “Architectural Sheet Metal Manual,” 7th edition, 2012.Includes Rain Intensity WizardThe calculator includes a Rain Intensity Wizard enabling the user to select the nearest city to their building and the information taken from the tables in the “Architectural Sheet Metal Manual.” The rain intensity according to Table 1-2 (Rainfall Data and Drainage Factors) uses a 5-minute duration for a 10-year or 100-year storm, thereby providing a worst-case scenario for the downspout and gutter design.Since the rain intensity data is constantly being updated by the National Oceanic and Atmospheric Administration (NOAA), this calculator also allows the user to manually enter the rainfall intensity. This feature allows one to use calculations according to the local authority with jurisdiction in that area. For the most up-to-date Rain Intensity Data, visit NOAA’s website and use “Precipitation Intensity” as the data type.Design Area WizardSMACNA’s new Downspout and Gutter Sizing Calculator enables the user to manually enter theGutter Cost Calculator – Estimate Gutter Installation Budget
In each DP size range, for the catchment area entered, and the recommended eaves gutter cross sectional area for the relevant downpipe size. It is recommended that all downpipes on a project are the same size, so if you prefer 100 dia downpipes, the calculator will tell you how many 100 dia DP's you need. Conversely if you can fit only say 2 downpipes, then the program will tell you what size you need. To mix and match sizes, split the roof into different catchments for each size. However, it is important when using this method, that all downpipes have a similar catchment area. Or the ability to share the flow. If this is not the case, it may be necessary to split the catchments, or calculate each downpipe catchment area individually. Roof Catchment Area: The roof catchment area (watch video on how to calculate from a PDF plan) is the plan area as shown on the drawings. Entering the roof slope in the next box makes the necessary adjustments for a sloping roof. Roof Slope: Enter the roof slope in degrees. Note: if your roof slope is shown as a percentage, or of the form 1 in ?, (Vertical:Horizontal) then use the 'conversion calculator' shown below. Roof Slopes for combined Roofs If the roof has multiple slopes, ie a steep slope draining to a flatter slope (or visa versa), the slope to use is the average slope. Take the plan length from ridge to gutter, divide by the total fall, this will give the 'x' in terms of the roof slope being '1 in x'. Enter the 'x' in the conversion calculator to get degrees. 'Degrees' must be used for the 'roof slope' box. For the 'Conversion calculator', enter in one box and the answer will appear in the relevant other. More info on how the roof slope affects the catchment area. Intensity: Click the drop down box to enter a location. This sets the rainfall intensity for that town. If your location is not on the list, refer below on how to find, and add your own intensity,How To Calculate The Size Of A Gutter - Sam's Gutters Ltd

Area" of each of their standard gutters. Enter this figure in the gutter area box, or select a gutter from the optional drop down list, then press calculate. The results don't seem to make much sense at first glance, so let's see what is happening:- We obviously need a whole number of downpipes to service the gutter. Standard Downpipes can increase in diameter by as much as 50%. So one number (n) of DP's may be not enough, and the next number (n+1) may be too many. Looking at it another way, let's say the chosen gutter can handle 2 L/s; but there is 7L/s draining to the gutter. If we split the gutter into 3 equal catchment areas (ie using 3 DP's), each will have 7/3 = 2.3L/s flowing into the DP and also flowing along that stretch of gutter. This flow is too much, as the gutter can only take 2L/s. Therefore we need a larger gutter, or more DP's. If we split the gutter into 4 equal catchment areas (one more DP) we have 7/4 = 1.75L/s flowing along the gutter. However the gutter can handle 2 L/s therefore we can use a smaller gutter. This is why the "gutter area for this flow" result in the program is smaller than the chosen gutter. Either way, in this example, we must use at least 4 downpipes . The most economical downpipe size to use is the "theoretical size" shown. This size can handle approximately the same flow that is flowing along the gutter. Note: the flow along the gutter is not necessarily the gutter capacity. To utilise the full gutter capacity would require a non whole number of downpipes. For instance, the example above would require somewhere between 3 and 4 down pipes. (three is not enough, and 4 is too many) However another solution is to use different size downpipes. One size to suit the chosen gutter size, and one size to suit any left over areas. For instance, the maximum catchment area for the chosen gutter has been calculated.
