Abstract
Present research expresses an experimental investigation on nanoparticle use to enhance Solar still (SS) yield. Manganese Oxide (MNO2) is selected as a nanoparticle material and used in SS. The nanomaterial is added with the black chrome paint of the SS walls to increase the yield. The weight concentrations (WC) of MNO2 have been used from 20% to 50 to see its effect on SS yield. It has been observed that the heat transfer and water temperature enhanced by the use of the MNO2 nanoparticle with black chrome paint. The use of the MNO2 nanoparticle has improved the yield of the SS. It has also observed that the yield of SS enhanced by 19.5% compared with alone SS by use of WC of 20–50%. The SS with MNO2nanoparticle's payback time is 82 days at 20% WC than the alone SS of 98 days.
