| Title: | Evaporação obtida em evaporímetros em forma de U e vertical comparada com a evaporação estimada pela Equação de Penman |

| Abstract: | O objetivo deste estudo foi analisar os valores de evaporação medidos com os evaporímetros em forma de U e vertical desenvolvidos nos Laboratórios de Recursos Hídricos e Termofluidodinâmica da COPPE/UFRJ pelos professores Cirus Macedo Hackenberg e Paulo Canedo de Magalhães. Os dados de evaporação medidos com o evaporímetro em U ao sol foram comparados com os estimados pela equação de Penman obtendo-se bons resultados. Os dados de evaporação medidos com o evaporímetro vertical foram comparados com os medidos pelo evaporímetro em U não se obtendo bons resultados nas comparações horárias. Os dados horários de evaporação estimados pela equação de Penman modificada foram comparados com os obtidos pelo evaporímetro em U ao sol e equação tipo seno obtendo-se bons resultados. |
| Abstract: | The purpose of this study was firstly to analyse evaporation by the use of U shaped and vertical evaporimeters which are being developed in the laboratories of Hidraulic Resources and Thermofluid-dynamics of COPPE-UFRJ by Cirus Macedo Hackenberg & Paulo Canedo de Magalhães, and secondly to test the Penman modified equation to avaluate hourly evaporation. The evaporation data obtained from the U shaped evaporimeter exposed to the sun, was analysed and also compared to the values supplied by the Penman equation. The results were good. The evaporation data obtained from the vertical evaporimeter was compared to the data obtained from the U shaped evaporimeter which had been exposed to the sun. Results obtained by hourly comparisons were not good. The hourly evaporation data supplied by the modified Penman equation were compared to both the data obtained by the U shaped evaporimeter exposed to the sun and the sine equation. Good results were obtained. |
