Saturated steam at a temperature of 65°C condenses on a vertical plate surface at 55°C. At a location 0.2 m from the plate top, determine the following parameters on the basis of per unit width of the plate. The fluid property values are: ρl = 985 kg/m3; ρv = 0.1614 kg/m3; kl = 0.6513 W/m.K; cp = 4183 J/kg.K; μl = 4.7083×10^– 4 kg/m.s; hfg = 2346.2 kJ/kg (use this value of hfg, where needed, without modifying it). a) find Thickness of the condensate film b) find condensate heat flow rate c) local convective heat transfer coefficient and condensate flow rate for (b=1)
