|- |font style="background: #ebebeb" colspan="3" | OperatingP - NOTE: this pressure is applied to the (combined) feed, before sub-models (if any). |- | valign="top" rowspan="5" | Method | AutoDetect|| If there are any liquids AND no vapours present in the feed, outlet streams will take the highest pressure of the feeds. Else (e.g. some vapours present) outlet streams will take the lowest pressure of the feeds. |- | LowestFeed || Outlet streams will take the lowest pressure of the feeds. |- | HighestFeed || Outlet streams will take the highest pressure of the feeds. |- | Atmospheric || Outlet streams will be at Atmospheric Pressure. The atmospheric pressure is calculated by SysCAD based on the user defined elevation (default elevation is at sea level = 101.325 kPa). The elevation can be changed on the Environment tab page of the Plant Model. |- | RequiredP || Outlet streams will be at the user specified pressure. |- | IgnoreLowMassFlow / IgnoreLowQm || Tick Box || This option is only visible if the AutoDetect, LowestFeed or HighestFeed methods are chosen. When calculating the outlet pressure and temperature of the tank, SysCAD will ignore the low flow feed streams should this option be selected. The low flow limit is set in the field below. |- | LowMassFlowFrac / LowQmFrac || Input || This field is only visible if the IgnoreLowQm option is selected. This is the amount any stream contributes to the total flow. For example, if the total feed to the tank is 10 kg/s, and this field is set to 1%. Then any feed streams with less than 0.1 kg/s will be ignored in the pressure calculations. |- | PressureReqd / P_Reqd || Input || This field is only visible if the RequiredP method is chosen. This is user specified pressure. |- | Result ||font style="background: #ebebeb"| Calc || The actual pressure used for the sum of the feeds which will also be the outlet pressure (unless further model options change the pressure).
