In the continuous flow method of Callender and Barnes the the potential difference across the wire was 3 volts and the current 2 amperes. The temperature of in flowing water was 20^(@)C and that of out flowing water 22.7^(@)C and 300g of water were collected in 10 minutes. When the p.d. was increased to 3.75 volts and the current to 2.5 amperes, the flow was adjusted to maintain the same temperature difference and 240g of water were collected in 5 minutes. Calculate the mean specific heat capacity of water at the mean temperature 21.35^(@)C.
