Experimental investigation on the yield of solar still using manganese oxide nanoparticles coated absorber

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