Description

Create a pump for the water hammer scenario using the method of characteristics. This feature allows you to add a specific pump to the simulation scenario, defining its main characteristics such as operation curves, efficiency, and installation conditions. It is particularly useful for simulating pump behavior under hydraulic transient conditions.

Calculation Method

The default method allows adding a pump to the water hammer scenario using the provided parameters to define the pump's operating conditions. These conditions include specific performance characteristics, such as head and power curves, efficiency, rotational speed, and installation setup (parallel pumps, suction elevation).

Inputs:

• Scenario: Identifier of the scenario where the pump will be added.
• Name: Name that identifies the pump.
• Head curve: ID of the pump's head curve.
• Power curve: ID of the pump's power curve.
• WR2: Moment of inertia of the pump's rotor.
• Efficiency: Efficiency of the pump in percentage.
• Rotation: Pump's rotational speed, with a default value of 1750 min⁻¹.
• Pumps in parallel: Number of pumps operating in parallel, with a default value of 1.
• Suction elevation: Height of the suction level.

Outputs:

• Scenario: The scenario configured with the new pump.
