class qsdsan.unit_operations.static._non_reactive.Copier(ID='', ins: Sequence[AbstractStream] | None = None, outs: Sequence[AbstractStream] | None = (), thermo=None, init_with='WasteStream', F_BM_default=1, **kwargs)¶

A non-reactive unit that simply copy all the influents to the effluents (in the same order), i.e., it does not affect stream flow.

Note that for a unit without the _run function and with only one influent, the effluent will be automatically copied from the influent, but this Copier class will work for any number of influents.

Parameters:

ins (Iterable(obj)) – Any number of influents, all will be copied to the effluents.
ins – Any number of effluents, all copied from the corresponding influents.

line: str = 'Copier'¶: class-attribute Name denoting the type of Unit class. Defaults to the class name of the first child class

run()¶: Run mass and energy balance. This method also runs specifications user defined specifications unless it is being run within a specification (to avoid infinite loops).

class qsdsan.unit_operations.static._non_reactive.LumpedCost(ID='', ins: Sequence[AbstractStream] | None = None, outs: Sequence[AbstractStream] | None = (), thermo=None, init_with='WasteStream', cost_item_name='Lumped cost', CAPEX=0.0, power=0.0, add_OPEX=0.0, **kwargs)¶

A non-reactive unit only for cost calculation purpose.

Parameters:

cost_item_name (str) – The name of this unit that will be shown in design, cost, and result dicts.
CAPEX (float) – Total installed capital cost.
power (float) – Total electricity usage.
add_OPEX (float) – Additional operating cost per hour.
