Carbon dioxide at 427?C is to be used to heat 12.6 kg/s of pressurized water from 37?C

Question:

Carbon dioxide at 427?C is to be used to heat 12.6 kg/s of pressurized water from 37?C to 148?C while the gas temperature drops 204?C. For an overall heat transfer coefficient of 57 W/(m2 K), compute the required area of the exchanger in square feet for(a) Parallel flow,(b) Counterflow,(c) A 2-4 reversed current exchanger, and(d) Crossflow, gas mixed.GIVENCO2 heating water in a heat exchangerCO2 temperaturesTg,in = 427?CTg,out = 427 ?? 204 = 223?CWater temperaturesTw,in = 37?CTw,out = 148?CWater flow rate (mw) = 12.6 kg/sOverall heat transfer coefficient (U) = 57 W/(m2 K)ASSUMPTIONSIn configuration (c), the gas is in the shellside
