Saturated liquid water at a flow rate of 100 kg/h and temperature of 110°C is to be heated in a convection section of a furnace by convective hot gas stream from the radiant section as illustrated in Figure 1 below. The hot gas stream enters the convection section at an average velocity of 6 m/s, pressure of 1 atm and temperature of 450°C. Stack -Convection Section -Bridgewall Radiant Section Burner Figure 1: Typical Configuration of a Furnace Tube banks are installed in the convection section in a staggered arrangement. There are 7 rows in the flow direction with 5 tubes in each row. The outer diameter of the tubes is 2.5 cm and the longitudinal and transverse pitches are S₁ = 4 cm and ST = 3 cm, respectively. Using the properties of air for the hot gas, determine the length of individual tube in the tube bank to heat the saturated liquid water to saturated vapour.
