voltage_list¶

list of voltage (the keys of preceding dictionaries) [V]

Type:	None or list,

specs¶

Dataframe with columns of following numeric:: ‘voltage’: voltage at pump input [V] ‘current’: current at pump input [A] ‘power’: electrical power at pump input [W]] ‘tdh’: total dynamic head in the pipes at output [m] ‘flow’: pump output flow rate [liter per minute]

Type:	None or pandas.DataFrame,

data_completeness¶

Provides some figures to assess the completeness of the data. (for more details, see pump.specs_completeness() )

Type:	None or dict,

__init__(path, motor_electrical_architecture=None, idname=None, price=nan, controller=None, diameter_output=None, modeling_method='arab')¶: Initialize self. See help(type(self)) for accurate signature.

Methods

`__init__`(path[, …])	Initialize self.
`functIforVH`()	Function computing the IV characteristics of the pump depending on head H.
`functIforVH_Arab`()	Function using Hadj Arab model for modeling I vs V of pump.
`functIforVH_Kou`()	Function using Kou model for modeling I vs V of pump.
`functIforVH_theoretical`()	Function using electrical architecture for modeling V vs I of pump.
`functQforPH`()	Function computing the output flow rate of the pump.
`functQforPH_Arab`()	Function using Hadj Arab model for output flow rate modeling.
`functQforPH_Hamidat`()	Function using Hamidat model for output flow rate modeling.
`functQforPH_Kou`()	Function using Kou model for output flow rate modeling.
`functQforPH_theoretical`()	Function using theoretical approach for output flow rate modeling.
`functQforVH`()	Function redirecting to functQforPH.
`iv_curve_data`(head[, nbpoint])	Function returning the data needed for plotting the IV curve at a given head.
`starting_characteristics`(tdh, …)	To Develop: In order to start, the pump usually need a higher power input than the minimum power input in steady state operation.
