20 kg/s of an organic vapor is being condensed at 360 K on the outside of a bundle of pipes through which water flows at 0.4 m/s; its inlet temperature being 290 K while outlet temperature shouldn't exceed 323 K. The outer and inner diameters of the pipes are 30 mm and 24 mm respectively. If the coefficients of heat transfer on the vapor and water sides are 1.8 and 3.2 kW/m2 K, how long should these be? What is the overall length of tubes, and what would a length of one tube be (how many tubes are there)? The latent heat of condensation is 330 kJ/kg. Neglect any resistance to heat transfer in the pipe walls. H=3.2 kW/mK for D Hio=hx(d;/do)=2.56 kW/mK
