6. Determine the effectiveness.

7. Calculate the total heat transfer rate.

This chapter has discussed the basic design methods for two fluid heat exchangers. The design techniques of recuperators and regenerators, which are two main classes, were investigated. The solution to recuperator problem is presented in terms of log-mean temperature difference (LMTD), effectiveness-number of transfer units (ε NTU), dimensionless mean temperature

8. Calculate the outlet temperatures.

3. Calculate C\*.

6. Conclusion

4. Calculate (Cr)\*. 5. Calculate NTUo.
