Water flows across the outside of a bank of tubes. It enters at 30C and leaves at 40C. The water enters at a flowrate of 34.27 kg/s, the shell diameter is 20 in, the baffle spacing is half () the shell diameter, the baffle cut (BC) is 15%, and -in outside diameter (OD) tubes on a 1-in pitch are used. The fluid inside the tubes may be assumed to be at a constant temperature of 90C (condensing organic), the inside coefficient is expected to be much higher than the shell-side coefficient, and thus the wall temperature may be taken as 90C. Use Kerns method to determine the average heat transfer coefficient for the shell side for Equilateral triangular pitch.

Water flows across the outside of a bank of tubes. It enters at 30C and leaves at 40C. The water enters at a flowrate of 34.27kg/s, the shell diameter is 20 in, the baffle spacing is half (1/2) the shell diameter, the baffle cut (BC) is 15%, and 3/4-in outside diameter (OD) tubes on a 1-in pitch are used. The fluid inside the tubes may be assumed to be at a constant temperature of 90C (condensing organic), the inside coefficient is expected to be much higher than the shell-side coefficient, and thus the wall temperature may be taken as 90C.
