| Abstract | ||
| The aim of the present study is to develop mathematical analysis for common design solar still involving all ambient surrounding variables affecting its productivity and coefficient of performance. Two similar units of the solar stills were used namely: Control unit and cooled glass cover unit (cooled unit). The prediction equations for the productivity of the two studied units were reasonably accepted with coefficients of determinations ranged between 98-99%. It was also found that the cooledunit has highest values of the productivity and coefficient of performance. The daily productivity and average coefficient of performance were 6.1655 kg/m2, 59.52% for the cooled unit compared to 5.536 kg/m2 and 52.19% for the controlunit. | ||
