This calculator helps you determine the volumetric flow rate of a fluid through a pipe. The flow rate is a crucial parameter in fluid dynamics and is essential for designing and analyzing pipe systems in various engineering applications, from plumbing and HVAC to industrial processes and chemical engineering.
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 pipe diameter and a non-negative number for fluid velocity.";
return;
}
// Calculate the cross-sectional area of the pipe: A = pi * r^2 = pi * (d/2)^2
var radius = diameter / 2;
var area = Math.PI * Math.pow(radius, 2);
// Calculate the volumetric flow rate: Q = A * v
var flowRate = area * velocity;
