Solar water heater plays an important role in energy conservation. Because of its efficiency is comparatively more than the electrical energy conversion. It has become the well proven and established appliance for providing hot water requirements in lacks of families in India. Solar water heater is a very simple device and efficient way to absorb energy from the sun rays and use it. Therefore improvement in their operating condition & geometrical would definitely result in saving conventional fuel and cost. The objective of this study is to validate the mass flow rate of water inside the collector tube in an ado-ekidi natural circulation solar water heater system. The existing solar water heating systems the optimum mass flow rate is 0.1 kg / m2 .The numerical analysis is carried out with CFD software and the results shows maximum mass flow rate inside the collector tube is 0.6 kg / m2 ,dynamic pressure of 4.30×105 Pa , flow velocity of 5.91×105 l/m2 & relative temperature of 360° K.
