We provide the following methods to provide a compositional approach for defining common variables used in petroleum flow models. These methods should always be defined over "AbstractPetroleumModel".
PetroleumModels.variable_demand_volume_flow — FunctionVariables associated with volume demand: $ql$
PetroleumModels.variable_head — Functionvariables associated with head: $h$
PetroleumModels.variable_production_volume_flow — FunctionVariables associated with volume production: $qg$
PetroleumModels.variable_pump_efficiency — FunctionVariables associated with pump efficiency: $\eta$
PetroleumModels.variable_pump_rotation — FunctionVariables associated with pump rotation: $w$
PetroleumModels.variable_tank_intake — Functionvariables associated with tank intake: $qin$
PetroleumModels.variable_tank_offtake — Functionvariables associated with tank offtake: $qoff$
PetroleumModels.variable_volume_flow_pipe — FunctionVariables associated with volume flow through a pipe: $q$
PetroleumModels.variable_volume_flow_pump — FunctionVariables associated with volume flow through a pump: $q$
