fractions, if input, must add up to 1.0 (unity).If mass fractions
are used and the total mass flowrate is input, the component mass
flowrates will be calculated by the program.

program may adjust the specific enthalpies of each stream to achieve
a heat balance (provided within 10% error)
In SIMULATION, the program will use this value for its first guess.
It is important to input a good value here.

pressure drop. For DESIGN calculations, enter the maximum allowable
pressure drop.

NOTE: This item is the PRESSURE DROP not the outlet pressure as

Enter the heat load if the total flowrate is defaulted (or outlet
quality if isothermal at the outlet). The heat load is only used to
calculate the flowrate (or quality).
In DESIGN and CHECKING the heat loads for each side should be the

be the same for each side. (The required heat load is the mean of
both sides in this case.)

TYPE OF CALCULATION
TASC3 has 3 modes of calculation
In modes 1 and 2 the geometry is known (sometimes called PERFORMANCE).
1) CHECKING   - calculate the area to give a given duty
2) SIMULATION - calculate the duty for a given area
3) DESIGN     - design an exchanger to do a given duty

NOTE: Only the first four characters are required.
      Once entered, it is not possible to change mode of operation.

COLD STREAM PROPERTIES
Enter 0 if the properties of the cold stream are to be
directly input (STREam data).
Enter the number of components if the cold stream properties
are to be calculated from COMPonent data.





HOT STREAM PROPERTIES
Enter 0 if the properties of the hot stream are to be
directly input (STREam data).
Enter the number of components if the hot stream properties
are to be calculated from COMPonent data.





NUMBER OF DATA POINTS (COLD)
Enter the number of data points to be input for the
cold temperature/enthalpy curve if using STREam data.
This item may be ignored if using COMPonent data






NUMBER OF DATA POINTS (HOT)
Enter the number of data points to be input for the
hot temperature/enthalpy curve if using STREam data.
This item may be ignored if using COMPonent data






COST DATA REQUIRED
Enter Y if COST data is required.
