Rate of Transpiration Calculator
This calculator helps you estimate the rate of transpiration in plants. Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores (stomata) in their leaves. Understanding transpiration rates is crucial for plant health, water management in agriculture, and ecological studies.
Calculate Rate of Transpiration
function calculateTranspirationRate() {
var waterAbsorbedInput = document.getElementById("waterAbsorbed");
var timeDurationInput = document.getElementById("timeDuration");
var leafAreaInput = document.getElementById("leafArea");
var resultDiv = document.getElementById("result");
var transpirationRateDisplay = document.getElementById("transpirationRate");
var unitRateDisplay = document.getElementById("unitRate");
var waterAbsorbed = parseFloat(waterAbsorbedInput.value);
var timeDuration = parseFloat(timeDurationInput.value);
var leafArea = parseFloat(leafAreaInput.value);
if (isNaN(waterAbsorbed) || isNaN(timeDuration) || isNaN(leafArea) ||
waterAbsorbed < 0 || timeDuration <= 0 || leafArea <= 0) {
transpirationRateDisplay.innerHTML = "Please enter valid positive numbers for all fields. Time duration and leaf area must be greater than zero.";
unitRateDisplay.innerHTML = "";
resultDiv.style.display = "block";
return;
}
// Formula: Rate of Transpiration = (Water Absorbed (ml) / Time Duration (hours)) / Total Leaf Area (cm²)
var rate = (waterAbsorbed / timeDuration) / leafArea;
transpirationRateDisplay.innerHTML = "Rate of Transpiration: " + rate.toFixed(4);
unitRateDisplay.innerHTML = "Units: ml/cm²/hour";
resultDiv.style.display = "block";
