class qsdsan.unit_operations.bst._abstract.FakeSplitter(ID='', ins: Sequence[AbstractStream] | None = None, outs: Sequence[AbstractStream] | None = (), thermo=None, init_with='WasteStream', include_construction=True, construction=[], transportation=[], equipment=[], add_OPEX={}, uptime_ratio=1.0, lifetime=None, F_BM_default=None, isdynamic=False, exogenous_vars=(), **kwargs)

Similar to biosteam.units.FakeSplitter, but can be initialized with qsdsan.SanStream and qsdsan.WasteStream.

line: str = 'Fake splitter'

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).

Similar to biosteam.units.Mixer, but can be initialized with qsdsan.SanStream and qsdsan.WasteStream, and allows dynamic simulation.

property state

The state of the Mixer, including component concentrations [mg/L] and flow rate [m^3/d].
