W = m3 = . kg A liquid (p = 1122 Milano : Cp = 3660 kqx; k = 0.5536 (p ; kg.K mri u = 0.01 Pa.s) at temperature of 290 K flows into pipe (inner diameter =12,7 mm, outer diameter = 15,7 mm) of a double pipe exchanger at a rate of 0.038 kg/s. In the outside of the pipe (annulus) there is steam condensing at 400 K. Position of pipe is horizontal. Out let temperature of liquid is 340 K. Determine flow rate of steam and length of pipe required (you have to determine forced heat transfer convection at inner surface of the pipe and condencing heat transfer coefficient at outer surface of the pipe)
