Hello,
I am using saturated steam at 6 bar on the shell side. This then condenses to water with no temperature change. Type of condensation is upon horizontal tube bundles.
Shell and tube heat exchanger is used.
1-2 pass.
Length of tubes is 4ft.
Outside diameter of the tubes is 16mm.
Flow rate of the steam is 0.133 kg/s
Velocity of steam is 1.5 m/s
Conductivity of steam is ~0.7 W/m.C
Number of tubes is 60
Estimated area from UAdT is 3.6 m
Fluid in the tubes is being heated from 90 to 100 degrees C.
Heat transfer coefficient I am getting is ~13500 W/m2.K
I understand this may not be all of the information required to calculate the heat transfer coefficient on the shell side but on face value, does 13500 seem right?
I personally think its way too high, was expecting ~6000-7000
