Water is being boiled in a flat bottom kettle placed on a stove. The area of the bottom is \[3000\text{ }c{{m}^{2}}\] and the thickness is 2 mm. If the amount of steam produced is 1 g/min. Calculate the difference of temperature between the inner and outer surface of the bottom. Thermal conductivity for the material of kettle is \[0.5\,cal/{{\,}^{o}}C/s/cm\] and the latent heat of steam is 540 cal/gm. |
