PARAMETERS
Inlet Flow
Select ‘Constant’ or the number of the channel supplying the measured fl ow rate. If
‘Constant’ selected, a further ‘box’ allows the value for the constant to be entered.
Use
Allows the user to select Temperature (˚C) or Pressure (MPa) for the calculation.
Inlet Temperature Appears only if Use = Temperature. Select ‘Constant’ or the number of the channel
supplying the steam temperature. If ‘Constant’ is selected, a further ‘box’ allows a
value for the constant to be entered.
Inlet Pressure
Appears only if Use = Pressure. Select ‘Constant’ or the number of the channel sup-
plying the steam pressure. If ‘Constant’ is selected, a further ‘box’ allows a value for
the constant to be entered.
Inlet Dryness
Enter a value between 0 and 100 to represent the dryness of the steam. 0 = no va-
pour; 100 = no liquid.
Return Temperature Select ‘Constant’ or the number of the channel supplying the condensate tempera-
ture If ‘Constant’ is selected, a further ‘box’ allows a value for the constant to be
entered.
*Note: See Saturated Steam Mass Flow, above, for details of
pressure unit conversion
GROUP MKT
Similar in operation to
MKT
, described above, except that the MKT is derived from a specifi ed group of
points rather than a single point. For each sample period, the maximum and minimum values reached by
any point(s) within the specifi ed group are saved, and used as inputs to the Equation.
