Understanding the flow rate of a fluid through a pipe is crucial in various engineering and scientific applications. This calculator helps you determine the volumetric flow rate based on the pipe's cross-sectional area and the fluid's velocity. The volumetric flow rate (Q) is the volume of fluid that passes through a given cross-section per unit time. It is calculated using the formula: Q = A * v, where 'A' is the cross-sectional area of the pipe and 'v' is the average velocity of the fluid.
To use this calculator, you need to know the internal diameter of the pipe and the velocity of the fluid flowing through it. The units you use for diameter and velocity will determine the units of the resulting flow rate. For instance, if you input diameter in meters and velocity in meters per second, the flow rate will be in cubic meters per second.
function calculateFlowRate() {
var diameter = parseFloat(document.getElementById("pipeDiameter").value);
var velocity = parseFloat(document.getElementById("fluidVelocity").value);
var resultDiv = document.getElementById("result");
if (isNaN(diameter) || isNaN(velocity) || diameter <= 0 || velocity < 0) {
resultDiv.innerHTML = "Please enter valid positive numbers for diameter and a non-negative number for velocity.";
return;
}
// Calculate the radius
var radius = diameter / 2;
// Calculate the cross-sectional area (A = pi * r^2)
var area = Math.PI * radius * radius;
// Calculate the volumetric flow rate (Q = A * v)
var flowRate = area * velocity;
