An iron boiler is 1 cm thick and has a heating area `2.5 m^(2)`. The two surface of the boiler are at `230^(@)C` and `100^(@)C` respectively. If the latent heat of the steam is `540 kcal kg^(-1)` and thermal conductivity of iron is `1.6xx10^(-2)K cal s^(-1) m^(-1)K^(-1)`, then how much water will be evaporated into steam per minute ?

An iron boiler is 10 mm thick and has a heating area 2m^(2) . The two surfaces of the boiler are at 240^(@)C and 100^(@)C respectively. Find the mass of the water evaporated into steam per minute. Given that latest heat of steam is 536 kcal kg^(-1) and thermal conductivity of iron is 1.6 xx 10^(-2) kcal s^(-1) m^(-1) .^(@)C^(-1) .

An iron boiler with walls 1.25 cm thick contains water at atmospheric pressure. The heated surface is 2.5 m^(2) in area and the temperature of the underside is 120^(@)C. Thermal conductivity of iron is 20 cal s^(-1) m^(-1) K^(-1) and the latent heat of evaporation of water 536 xx10^(3) cal kg^(-1) . Find the mass of water evaporated per hour.

An iron plate 10^(-5) m^(2) area, 4 xx 10^(-3) m thick has its opposite faces maintained at 373 K and 223 K respectively. How much heat flows through the plate per second ? Thermal conductivity of iron = 80 "Wm"^(-1) "K"^(-1) .

1 g of a steam at 100^(@)C melt how much ice at 0^(@)C ? (Length heat of ice = 80 cal//gm and latent heat of steam = 540 cal//gm )

How much steam at 100^(@) C is to be passed into water of mass 100g at 20^(@)c to raise its temperature by 5^(@)C ? (Latent heat of steam is 540 cal /g and specific heat of water is 1 cal // g^(@)C )
