1.	An iron boiler with walls 1.25cm thick contains water at atmospheric pressure. The heated surface is 2.5m^(2) in ara and the temperature of the underside is 120^(@)C. Thermal conductivity of iron is 20cals^(-1)m^(-1)K^(-1) and the latent heat of evaporatioin of water 536xx10^(3) cal kg^(-1) (J=4.2Jcal^(-)). Find the mass of water evaporated per hour.
Answer» ANSWER :`537.3kg` PER HOUR
