Water, a basic human need can be purified by different techniques like membrane distillation, boiling and solar still. Among all types, still is considered to the most economical simpler one. In this study, geometrical aspects of for Karachi varying tilt has been simulated. The study conducted height length keeping constant glass surface area cover while basin area. between time duration from 08:00 18:00 hours which generally sunshine Karachi. simulation results are verified with experimental shows good agreement each other. For area, maximum mass production water observed at 60° 24.8° equal latitude both cases, temperature around 13:00 hours.
