Summary of the major data types.

Available from the Data Selection menus in the menu bar.  Note that additional data and data subsets are available in the spreadsheet view.

Flow        

Quantity        The volume flow rate of liquid/slurry through a pipe.

Velocity        The average speed of flow through a pipe across the cross-sectional area.

Mass Flow        The mass flow through a pipe.  This is a function of volume flow and density.  Note that this will not necessarily be equal to the quantity x wet density value, because the mass flow does not consider the moisture component that is included in the density value.

Reynolds        The Reynolds describe the effect of viscosity on the fluid. If it is lower  than 2100 it will be a laminar flow, if it is higher than 4000 it will be turbulent

Pressure

Pressure Total Loss        The total pressure loss along a pipe between entry and exit.  Pressure loss may consist of pipe friction pressure losses, due to wall friction factors and additional resistances placed in the pipe.

Pressure Gauge        The pressure inside a pipe, corrected by the atmospheric pressure.  The correction removes the effect of elevation on pressure, and permits a relative assessment between pipes at different elevations.

Pressure Friction Loss        The loss of pressure along a pipe due to wall friction.  This ignores any other resistances in the pipe such as doors or stoppings.

Note that by default, atmospheric density is adjusted for temperature gradient (lapse) rate, in much the same way as auto compression can drive changes in underground temperature at different elevations.  Inlet pipes at different elevations will have different temperatures which are derived from the standard elevation and default surface temperature.  This function can be turned off (surface temperature adjust) in the settings if desired.

Pipe Attributes

Roughness        Roughness of the pipe; this value also represents the material.

Dimensions        The size of a pipe width and height as the centre section.

Perimeter        The perimeter of a pipe, calculated from the centre height and width, taking into account the pipe shape profile.  The perimeter can also be set directly from the EDIT menu.

Area        The area of a pipe, calculated from the centre height and width, taking into account the pipe shape profile.  The area can also be set directly from the EDIT menu.

Length        The true length of a pipe, used to calculate pipe resistance and heat transfer.  It does not include additional shock lengths if specified.

Coordinates        Report the coordinates of a pipe in eastings, northings and elevation.

Descriptors

Pipe Number        The internal array number of a pipe, referenced by Pumpsim™.  Pumpsim™ will report this number in error descriptions.  The pipe number may change as pipes are added or removed from the model.

Pipe Name        The name of a pipe branch.  The name can be entered in the pipe EDIT box.  The name does not affect simulation but may assist the user in identifying or finding pipes.

Unique ID Number        A unique number assigned to every pipe, that does not change when pipes are added or removed.  As a result, the numbers may not be sequential and may have large gaps in the sequence.

Pipe Type        The descriptive name of the pipe type set in the EDIT box.

Profile        The descriptive name of the profile if set.

Friction Factor        The Darcy Weisbach friction factor.

Primary Name        The name and number of a pipe primary layer.

Secondary Name        The name and number of a pipe secondary layer.
