Step-by-step Instant Solution


Water at an average temperature of 1070C and an average velocity of 3.5 m/s flows through a 5-m-long stainless steel tube (.2 W/m. 0C) in a boiler. The inner and outer diameters of the tube are Di = 1.0 cm and D0 = 1.4 cm, respectively. If the convection heat transfer coefficient at the outer surface of the tube where the boiling is taking place is

h0 = 8400 W/m2. 0C, determine the overall heat transfer coefficient Ui of this boiler based on the inner surface area of the tube. ?????????????????????????
