Saturated methyl chloride at 62 psia condenses on a horizontal bank of tubes, ten-by-ten, 2 in. OD, equally spaced, 4 in. apart center-to-center on rows and columns. If the surface temperature of the tubes is maintained at 45?F by water pumped through them, calculate the rate of condensation of methyl chloride in lbm/(h ft).The properties of saturated methyl chloride at 62 psia are shown belowSaturation temperature = 60?FHeat of vaporization = 167 Btu/ lbmLiquid density = 58.8 lbm/ft3Liquid specific heat = 0.38 Btu/(lbm ?F)Liquid absolute viscosity = 1.344 x 104 lbm/(ft s)Liquid thermal conductivity = 0.10 Btu/(h ft?F)GIVENSaturated methyl chloride condensing on a ten-by-ten bank of horizontal tubesPressure = 62 psiaTube outside diameter (D) = 2 in = 1/6 ftTube center-to-center spacing (s) = 4 in = 1/3 ftMethyl chloride properties given aboveTube surface temperature (Ts) = 45?FASSUMPTIONSSteady stateLaminar flow condensationInterfacial shear is negligibleTube surface temperature is uniform and constantVapor density is negligible compared to the liquiddensity
