A pot with a steel bottom 1.2 cm thick rests on a hot stove. The area of the bottom of the pot is `0.150m^2`. The water inside the pot is at `100^@C and 0.440 kg` are evaporated every 5.0 minute. Find the temperature of the lower surface of the pot, which is in contact with the stove. Take `L_v = 2.256 xx (10^6) J//kg and k_(steel) = 50.2 W//m-K` .

A brass boiler has a base area of 0.15 "m"^(2) and thickness is 1.0 "cm" . It boils 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 boiler. Thermal conductivity of brass = 109 "Wm"^(-1) "K"^(-1)

Water is boiled in flat bottom kettle placed in a stove. The area of the bottom is 3000 cm^2 and the thickness is2 mm. If the amount of steam produced is 1 g min^(-1) . Then, the difference of temperature between inner and outer surfaces of the bottom is [K, for the material of kettle is 0.5 cal^0 C ^(-1) s^(-1) 1 cm ^(-1)]

A brass boiler has a base area of 0.15 m^(2) and thickness 1.0 cm. It boils 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 boller. Thermal conductivity of brass = 109 J s^(-1) m^(-1) K^(-1) , Heat of vaporisation of water = 2256 xx 10^(3) J kg^(-1) .

A brass boiler has a base area of 0.15 m2 and thickness 1.0 cm. It boils 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 boiler. Thermal conductivity of brass = 109 J s ^-1m^- 1K^-1 , Heat of vaporisation of water = 2256 xx 10^3 J kg^-1 .

A flat bottomed metal tank filled with water is dragged along a horizontal floor at the rate of 20 m//s The tank is of mass 100 kg and contains 900 kg of water and all the heat produced in the dragging is conducted to the water through the bottom plate of the tank. If the bottom plate has an effective area of conduction 1m^(2) and thickness 5 cm and the temperature of water in the tank remains constant at 50^(@) C, calculate the temperature of the bottom surface of the tank. Given the coefficient of friction between the tank and the floor is 0.5 and K for the material of the tank is 100 J//m sec K.
