*2.2.3 Experimental investigation to find the effect of PCM on solar distillation*

The PCM material was evenly distributed and covered by a 5-mm thick metal plate. The sides of the metal plate were sealed using M-Seal chemical to avoid leakage or contact of PCM and water. The same solar distillation experiments were conducted with a fixed amount of different PCM, and the distillate collected was

recorded on an hourly basis; 5 kg of phenol as PCM was used to perform the experiments at 0.05 and 0.07 m.
