This unit model is formulated as a single-input, double-output model form. See documentation for :ref:`single-input, double-output Helper Methods<sido_methods>`.
Electricity consumption is calculated using the constant_intensity helper function. See documentation for :ref:`Helper Methods for Electricity Demand<electricity_methods>`.
Costing is calculated using the :py:meth:`~watertap.core.zero_order_base.ZeroOrderBaseData.cost_power_law_flow` method. For full details on costing, see documentation for the :ref:`zero-order costing package<zero_order_costing>`.
