In this study, the performance of single slope solar stills inclined at 150, 300 & 450 have been investigated and compared to Dunkle model. It is found that the performance of present model is higher than that of Dunkle model. For the purpose of experiment constant temperature water bath has been used to maintain the steady state of water temperatures ranging from 40o C to 70o C. The yield obtained at an interval of every 30 minutes has been used to determine the values of constants C and n and consequently the performance parameters, internal heat transfer coefficients and internal mass transfer. The maximum internal mass transfer is obtained for condensing cover with inclination angle of 450 and the minimum for condensing cover with inclination angle of 150. The maximum and minimum percentage deviation in yield between the theoretical and practical values for condensing cover with inclination of 45° is -10.52% for 70° C & -1.96% for 45° C respectively.

Key words: Solar Distillation, internal heat and mass transfer, inclination angle, condensing cover
