Circulation Pump Mass

Create Function

create_circ_pump_const_mass_flow(net, from_junction, to_junction, p_bar, mdot_kg_per_s, t_k=None, name=None, index=None, in_service=True, type='pt', **kwargs)

Adds one circulation pump with a constant mass flow in table net[“circ_pump_mass”].

Parameters

• net (pandapipesNet) – The net within this pump should be created

• from_junction (int) – ID of the junction on one side which the pump will be connected with

• to_junction (int) – ID of the junction on the other side which the pump will be connected with

• p_bar (float) – Pressure set point

• mdot_kg_per_s (float) – Constant mass flow, which is transported through the pump

• t_k (float) – Temperature set point

• name (str) – Name of the pump

• index (int, default None) – Force a specified ID if it is available. If None, the index one higher than the highest already existing index is selected.

• in_service (bool, default True) – True for in_service or False for out of service

• type (str, default "pt") –

  The pump type denotes the values that are fixed:

  • ”p”: The pressure is fixed.

  • ”t”: The temperature is fixed and will not be solved. Please note that pandapipes cannot check for inconsistencies in the formulation of heat transfer equations yet.

  • ”pt”: The pump shows both “p” and “t” behavior.

• kwargs (dict) – Additional keyword arguments will be added as further columns to the net[“circ_pump_mass”] table

Returns

index - The unique ID of the created element

Return type

int

Example

>>> create_circ_pump_const_mass_flow(net, 0, 1, p_bar=5, mdot_kg_per_s=2, t_k=350, type="p")
