Size a pipe from the numbers you already have. Pipe Diameter Calculator finds the internal diameter of a circular pipe from your flow rate and target flow velocity, or checks the velocity in a pipe whose internal diameter you already know. Built for quick line sizing on site, at the desk or in class, it suits piping, mechanical and process engineers, plumbing and HVAC professionals, pipefitters and engineering students. TWO WAYS TO CALCULATE ā¢ Find the internal diameter: enter the flow rate, fluid density and target velocity ā¢ Check flow velocity: enter a known internal diameter and the flow rate VOLUME OR MASS FLOW ā¢ Start from a volume flow rate or a mass (weight) flow rate ā¢ Choose your inputs and the value to solve for on the Selection screen CLEAR RESULTS ā¢ Cross-sectional area of the pipe ā¢ Weight (mass) flow rate ā¢ Flow velocity ā¢ Internal pipe diameter METRIC AND IMPERIAL UNITS ā¢ Pick a unit for each input and each result from its own menu ā¢ Mix units freely, for example enter the diameter in centimeters and read the velocity in feet per second SIMPLE AND PRIVATE ā¢ One clean screen, a Calculate button and a one-tap clear button ā¢ Free to download ā¢ No data collected HOW IT HELPS DAY TO DAY ā¢ Pick a starting pipe size for a new line before you check it against your design standard ā¢ Check whether the velocity in an existing pipe is reasonable for the duty ā¢ Work through flow and velocity exercises for coursework and exams Results are a quick engineering estimate based on the values you enter. Always confirm final pipe sizes against the codes, standards and design criteria that apply to your project. Download Pipe Diameter Calculator and size your next line in seconds.
