A brass boiler has a base area of `0.15 m^2` and thickness 1.0 cm it bolis water at the rate of 6.0 kg/min, when placed on a gas stove. Estimate the temperature of the part of the flame in contact with the bolier. Thermal conductivity of brass ` =609 J s^(-1) .^@C^(-1).` Heat of vaporisation of water ` =2256 xx 10^3 J g^(-1)`

Explanation

since the pressure depends upon the height of water column and the height of the water column in the two vessels of different shapes is the same, hence there will be same pressure due to water on the base of each vessel. As the base area of each vessel is
