The condenser of a steam power plant contains N = 1000 brass tubes (k = 110 W/m.K), each of inner and outer diameters, D, = 25 mm and D. = 28 mm, respectively. Steam condensation on the outer surfaces of the tube is characterized by a convection coefficient h, = 10,000 W/m².K a) If cooling water from a large take is pumped through the condenser tubes at m, = k = 400 kg/s, what is the overall heat transfer coefficient U, based on the outer surface area of a tube? b) If after extended operation, fouling provides a resistance of R's = 1oʻm².K/W, at the inner surface, what is the value of U,? c) If m, is increased by 15% of the initial, what will be the value of U.? d) If water is extracted from the lake at 15°C and 10 kg/s of steam at 0.0622 bars are to be condensed, what is the corresponding temperature of the water leaving the condenser?
