In the constant flow moethof of callendar and Barnes it was found that when the rate of flow water was 11g per minute the heating current was 2 amperes and the difference in potential between the ends of the heating wire was 1 volt, the rise in temperature was 2.5^(@)C. On increasing the rate of flow to 25.4g per minute, the heating current to 3 amperes and the p.d.to 1.51 volts, the rise of temperature of water was still 2.5^(@)C.Calculate the value of J.
