Question: A single-pass, cross-flow heat exchanger uses hot exhaust gases (mixed fluid) to heat water flowing at a rate of 3kg/s to 80C. The exhaust gases, having thermophysical properties similar to air, enter and exit the exchanger at 225C and 100C, respectively If the overall heat transfer coefficient is 200W/m2.K. a) Draw a complete schematic with the temperature profile. b) Estimate the required surface area using LMTD method, Hint assume initial temperature of water =30C and the correction factor (F)=0.889.
