We report the experimental analysis of a pyramid solar still with boosting mirror system for increasing the distillate yield rate under clear climatic conditions in Coimbatore (11° N latitude), India. The radiation received by the still is boosted up by reflecting the solar radiation. A tracking system keeps track of incident radiation into the still. The area of the still is 0.25 m2. Water and ambient temperature are measured along with solar radiation and humidity at regular intervals of time. The inner and outer faces of the glass cover temperatures are also recorded. The average solar radiation received is 760.43 W/m2. The daily average efficiency of the still was found to be 15%. A 2.9 l/m2/d distillate yield is obtained with the help of the boosting mirror; whereas, 1.52 l/m2/day are collected without the boosting mirror. In this work an attempt has been made to study the effect of heat transfer within a pyramid solar still. The thermo physical properties of the still are analyzed for this study. Thermal conductivity dynamic viscosities of water are also studied for this system. The thermal conductivity is in the range of 26.77 x 10-2 Wm-2 C-1 to 29.64 Wm-2 C-1. Dynamic viscosity ranges from 18.6 x 10-6 Nsm-2 to 20.2 x 10-6 Nsm-2.
