2. In a condenser steam flows outside the tubes of radius 59 mm and 54 mm and sea water flows inside the tubes. The thermal conductivity of the tube material is 60 W/mK. The steam and water temperatures are below 50'C. The convection coefficient on the steam side is 12000 W/m: K and the value on the water side is 650 W/m K. Calculate the values of overall coefficients based on the (i) inside and (ii) outside areas. (Assignment)
