Problem: Consider fully-developed flow of water through a 24-cm diameter tube. The water comes in at 20°C and exits at 40°C. The surface temperature of the tube is uniform at 60°C. The water flow has a mass flow rate of 0.24 kg/s. What is the average convection coefficient of the water flow? Solution: We have T, = 60°C, Tmi = 20°C, Tmo = 40°C, So, the bulk-mean temperature is Tm = 30°C. The appropriate properties are: u = 7.98 × 10-4 kg/ms; k = 0.615…
