Heat Exchanger Rating Calculator does the Rating calculation for Shell and Tube Heat exchanger using Taborek version of Bell-Delaware Method. It evaluates the thermo-hydraulic performance of a fully specified exchanger.

It allows user to choose from following different modes of rating calculation.

• All Variables Known - In this mode all 6 variables namely Wt,Ws,t1,t2,T1,T2 are known and the application calculates the area required for this duty. Then it compares with Area Available in exchanger and reports Overdesign %.
• t1 & T1 Unknown - (Tube Inlet and Shell Inlet Temperature Unknown)
• t1 & T2 Unknown - (Tube Inlet and Shell Outlet Temperature Unknown)
• t1 & Ws Unknown - (Tube Inlet Temperature and Shell Mass flowrate Unknown)
• t2 & T1 Unknown - (Tube Outlet and Shell Inlet Temperature Unknown)
• t2 & T2 Unknown - (Tube Outlet and Shell Outlet Temperature Unknown)
• t2 & Ws Unknown - (Tube Outlet Temperature and Shell Mass flowrate Unknown)
• Wt & T1 Unknown - (Tube Mass flowrate and Shell Inlet Temperature Unknown)
• Wt & T2 Unknown - (Tube Mass flowrate and Shell Outlet Temperature Unknown)

For calculation of unknown variables either user can provide his own trial values or calculator can start with its trial value. This calculator provides a handy tool for plant engineers who want to quickly evaluate the performance of their heat exchangers.
