Im not quite sure if i got the question but yes: You can calculate the heat transfer coefficient. For water as for any liquid or gas you need:
-Thermal conductivity of liquid, k (water 0.59 kW/m C)
-Heat capacity, Cp (water: 4190 J/kg C)
-Viscosity, visc (water 0.001 kg/m s)
-Density, den (water 1000 kg/m3)
- Pipe diameter, D (m)
- Flow, V (m3/s)
1) Calculate Reynolds no.
Re= V*D*den/visc
2) Calculate Prandtls no:
Pr=Cp*visc/k
Use the correlation by Nussel:
Nu=0.023*Re^.8*Pr^.33
and
Nu=h*D/k
where h er the inside/ouside heat trabsfer coefficient.
When calculating from the outside (assuming the problem conserns pipe in pipe HX) use hydraulic diameter for D and calculate liquid velocity based on free area between pipes.
This is 100% standard heat transfer theory and any text book on the subject should tell you this.
