Description
Manual input flowing density: If
Flowing Density value is available
in the Flow element calculation
report, check manual input and
enter the value. Otherwise uncheck
manual input. Flowing density will
be calculated using Design Density
or density coefficients that will be
auto-calculated for the selected
fluid under Fluid list. When density
coefficients are passed to the
device, device calculates flowing
Density using the density
coefficients. Manual input available
for Advanced algorithms only.
Manual input flowing viscosity: If
viscosity value is available in the
Flow element calculation report,
check manual input and enter the
value. Otherwise uncheck manual
input, and viscosity coefficients will
be auto-calculated for the selected
fluid under Fluid list. Device will
calculate viscosity using the
viscosity coefficients. Manual input
available for Advanced algorithms
only.
Manual input Coefficient of
Discharge. Check the Manual input
and enter Coefficient of discharge
value from Flow element calculation
report. If value is not available,
uncheck the Manual input. Device
will auto-calculate the Cd value
based on fluid type, Flow element
and material selected. Manual input
applicable to Advanced algorithms
only. Cd is the ratio of actual
discharge through a nozzle or
orifice to the theoretical discharge.
It is related to the flow and pressure
loss through nozzles and the
orifices in the fluid systems.
Manual input gas expansion factor.
Check this and enter gas expansion
factor from flow calculation report.
Unselect this to have the device
auto calculate the gas expansion
factor. Y is a Correction factor to
compensate for the changes in fluid
properties due to expansion."
