Abstract

Evaporation from the water surface is one of the important topics in management and decision making for water resources. For this reason, measuring the evaporation rate is highlighted. In this study, the evaporation equation is determined with appropriate accuracy by constructing a laboratory device at first. Then, the evaporation rate of the water surfaces covered with photovoltaic panels is calculated and presented in the form of a new experimental equation. The proposed experimental equation is examined and analyzed in different modes and is validated by laboratory data. According to the results, the predicted value by this equation has an average error of about 10.53%, which is acceptable compared to other equations. According to the results, the application of photovoltaic panels on the lake dam surface by 25, 50, 75, and 100% reduces water evaporation by 16.36, 23.28, 43.28, and 69%, respectively. This indicates less evaporation in the surface covered by the panel.

确定一个估算有光伏板覆盖的水面蒸发的方程

水面蒸发量是水资源管理和决策中的重要课题之一。由于这个原因，测量蒸发速率是突出的。在本研究中，首先通过构建一个实验室装置来确定适当精度的蒸发方程。然后，计算了光伏板覆盖水面的蒸发速率，并以新的实验方程的形式给出了蒸发速率。在不同的模式下对所提出的实验方程进行了检验和分析，并通过实验数据进行了验证。结果表明，该方程的预测值平均误差约为10.53%，与其他方程相比，是可以接受的。结果表明，光伏板在湖坝面应用25%、50%、75%和100%分别减少了16.36%、23.28%、43.28%和69%的水分蒸发。这表明被面板覆盖的表面蒸发较少。图形抽象
