A 7.5cm diameter iron pipe carries steam at a pressure of 7.12atm (167C). The line is unlagged and is 60m long. It losses heat to the surroundings by conduction, convection and radiation. The surroundings are at 30C. The emissivity of the pipe wall is 0.7 and the view factor may be assumed to be unity. The convection heat transfer coefficient may be taken as 7.0 kcal/hr mC. If the latent heat of steam is 500 kcal/Kg. How many kilograms of steam will condense per hour. =4.87510-8Kcal/hr m2K 4
