摘要：Present research expresses an experimental investigation on nanoparticle use to enhance Solar still (SS) yield. Manganese Oxide (MNO 2 ) 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 MNO 2 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 MNO 2 nanoparticle with black chrome paint. The use of the MNO 2 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.
