# Known Pressure

Known Pressure (or Assigned Pressure) elements are entry or exit network points where the pressure is known or is a design condition. The flow direction to a Known Pressure component depends on the network system and is determined by FluidFlow. It is only possible to make one pipe connection to this type of component. Known Pressures can be used to represent tanks or vessels or any point in a network where a fluid leaves or enters. FluidFlow calculates the flow into or out of this element.
