The guidelines in TABLE 1 beneath relates to a particular heat exchanger. A reliable colleague has regarded up an effectiveness chart and says that the effectiveness within the given working stipulations is 0.55. Knowledge: \u2018Hot\u2019 fluid \u2018Cold\u2019 fluid Mass flowrate kg s-1 0.7 0.4 Particular heat means kJ kg-1 Okay-1 1.44 4.2 Inlet temperature \u05a9C 130 18 Total heat switch coefficient 112 W m-2 Okay-1 Dwelling of heat switch floor 9 m2 Opt: (i) The outlet temperature of the contemporary fluid. (ii) The outlet temperature of the cool fluid. (iii) The warmth switch fee. Calculate the correction factor. Dry saturated steam at a temperature of 180\u00baC is to be produced in a fireplace tube boiler from the cooling of 40 000 kg h-1 of flue gases from a pressurised combustion course of. The gases enter the tubes of the boiler at 1200\u00baC and leave at 250\u00baC. The feed water is externally preheated to 180\u00baC before getting into the boiler. (Recount the exchanger is counter-float) The indicate particular heat means of the flue gases is 1.15 kJ kg-1 Okay-1. Feed water temperature = 180\u00baC. (a) Gain the log indicate temperature distinction (b) Calculate the heat switch fee (c) Opt the situation of heat switch required to carry out this responsibility if the general heat switch coefficient according to the skin situation of the tubes is given as forty five W m-2 Okay-1. The tubes at some stage within the boiler are to be 38 mm inner diameter with a wall thickness of 4 mm. The everyday flue gas velocity through the tubes to care for the general heat switch coefficient mark and to minimise stress losses is to be greater than 20 m s-1 and no longer more than 26 m s-1. The everyday density of the flue gases is 1.108 kg m-3. Calculate the minimum and maximum preference of tubes in every plod Calculate the general dimension of tubes at every of these numbers of tubes Gain the minimum preference of tube passes in every case, if the scale of a boiler tube is to be much less than 4 metres.<\/p>\n","protected":false},"excerpt":{"rendered":"
