Meyer公式で水面積・水温・気温・湿度・風速から日/月の蒸発量を計算します。
Enter your pool surface area, water temperature, air temperature, relative humidity, and wind speed. The calculator uses the Meyer formula to estimate evaporation rate based on the vapor pressure difference between the water surface and air.
Higher water temperature, lower humidity, and more wind all increase evaporation. A pool cover can reduce evaporation by 90–95%, significantly cutting water and heating costs.
The results show daily, weekly, and monthly water loss in gallons and liters. Use these numbers to plan your refill schedule and estimate chemical dilution from makeup water.
