Tensile tests were made on polypropylene films as a function of aging temperature from 80 to 130ΠC at a strain rate of 5 cm min 01 . Polypropylene films aged at 60 and 100ΠC and at time intervals up to 180 min were also stretched at the same strain rate. The yield stress and initial modulus were fou
The effect of water depth on daily yield of a still has been studied using a transient analysis of a solar still. It is found that the dependence of yield on water depth is a strong function of initial temperature of the brine in the basin of the still. It is concluded that the daily yield increases
