6. Design calculations are performed based on the specifications given for the heat exchanger 7.
Heat transfer coefficient for steam is assumed to be 8000 W/m2*C8. Counter-current flow is assumed 9. Condensing steam is in the shell side due to changing in the volume requirement 10.
No leakage is incorporated Here are the steps for rating of Heat Exchanger1. Compute Energy balance2. Select heating medium (Given)3. Compute utility flowrate4.
Compute physical properties 5. Allocate fluids side 6. Decide the exchanger type7. Determine LMTD 8. Select value of overall coefficient, U9. Estimate the tentative area requirement10. Estimate the actual area (based on given geometry)11.
Calculate the shell and tube side heat transfer coefficient 12. Calculate the overall coefficient 13. Calculate heat transfer rate
