Determine the heat transfer coefficient for water flowing in a tube of 16 mm diameter at a velocity of 3 m/s. The temperature of the tube is 297 K (24°C) and the water enters at 353 K (80°C) and leaves at 309 K (36°C). Using (i) Dittus - Boelter equation and (ii) Sieder-Tate equation. Data : Properties of water at 331 K (58°C), i.e., at arithmetic mean-bulk temperature are : p = 984.1 kg/m, Cp = 4187 J/(kg:K), u = 485 x 106 Pa.s, k = 0.657 W/(m·K) Viscosity of water at 297 K (24°C), Uw 920 x 10-6 Pa.s
