This calculator helps you determine the required exhaust flow rate for a given room or area. Understanding exhaust flow rate is crucial for proper ventilation, ensuring air quality, and maintaining safe operating conditions, especially in industrial or laboratory settings.
function calculateExhaustFlowRate() {
var roomVolume = parseFloat(document.getElementById("roomVolume").value);
var airChangesPerHour = parseFloat(document.getElementById("airChangesPerHour").value);
var resultElement = document.getElementById("result");
resultElement.innerHTML = ""; // Clear previous results
if (isNaN(roomVolume) || isNaN(airChangesPerHour) || roomVolume <= 0 || airChangesPerHour <= 0) {
resultElement.innerHTML = "Please enter valid positive numbers for Room Volume and Air Changes Per Hour.";
return;
}
// Calculate exhaust flow rate in cubic meters per hour
var exhaustFlowRateM3h = roomVolume * airChangesPerHour;
// Calculate exhaust flow rate in liters per second
var exhaustFlowRateLps = exhaustFlowRateM3h * 1000 / 3600;
