GIS-IDs: List of associated IDs on the GIS/data-source side.
Hyperlinks: Associate one or more web link, photo, word processing document, or other file with this element.
Time (Delay until Valve Operates): The time delay prior to operating the spherical valve.
Time For Valve To Operate: Time required to operate the spherical valve. By default, it is set equal to one time step.
Diameter (Spherical Valve): The diameter of the spherical valve.
Efficiency: The efficiency of the turbine. A typical value is 90.
Moment of Inertia: The (weight) moment of inertia accounts for the turbine, generator, and entrained water.
Speed (Rotational): Also known as synchronous speed for a turbine. The power it generates depends on it.
Pattern (Gate Opening): Operating Rule describes the percent wicket gate opening vs time.
Specific Speed: This represents the type of turbine. HAMMER ships with 4-quadrant curves for: 30, 45, or 60 (US units), 115, 170, or 230 (metric units). You can add your own curves to this library.
Flow (Rated): Nominal or rated flow of the turbine.
Head (Rated): Nominal or rated head of the turbine.
Turbine Curve: Turbine Curve is only required for a steady run. For a transient run, HAMMER uses a 4-quadrant curve based on Specific Speed, Rated Head and Rated Flow.
Electrical Torque Curve: Defines the time vs torque response for the turbine. Only applies to the Load Rejection operating case.
Report Period (Transient): Number of time steps between successive printouts of operation. By default, this printout is suppressed.
Status (Initial): Choices: Open, Closed
Elevation: Elevation at centroid of junctions, valves, and pumps; the ground elevation at tanks; the hydraulic grade at reservoirs.
Concentration (Initial): Specify the initial concentration for the global concentration at the selected element.
Age (Initial): Specify the initial age of the fluid at the selected element.
Installation Year: Specify the install year of the element. It does not affect the calculations.
Trace (Initial): Specify the initial trace amount at the current location.
Zone: Specify the zone for the element.
Flow: Total flow through the turbine.
Headloss: Change in head across turbine.
Hydraulic Grade (From): Calculated hydraulic grade at the entrance of the turbine.
Hydraulic Grade (To): Calculated hydraulic grade at the exit of the turbine.
Pressure (From): Calculated pressure at the entrance of the turbine.
Pressure (To): Calculated pressure at the exit to the turbine.
Flow (Absolute): Magnitude of flow through the selected turbine.
Age (Calculated): Age at selected element for current time step.
Trace (Calculated): Trace at selected element for current time step.
Concentration (Calculated): Concentration at selected element for current time step.
Has Calculation Messages Now?: If true then the current element has associated calculation warning messages for the current time step.
Is Closed?: True if the current element is closed during the current time step.
Is Open?: Set to true if open during the current time step.
Is Initially Closed?: If true, the initial condition for the control element is "Closed" or "Off."
Controlled?: Is true if a control action in the current control set references the selected element.
Cannot Deliver Flow or Head?: If true then the cannot deliver head or cannot deliver flow warning was generated for the element for the current time step.
Head (Maximum, Transient): Maximum head at node over the course of the transient simulation.
Head (Minimum, Transient): Minimum head at node over the course of the transient simulation.
Pressure (Maximum, Transient): Maximum pressure at node over the course of the transient simulation.
Pressure (Minimum, Transient): Minimum pressure at node over the course of the transient simulation.
Air Volume (Maximum, Transient): Maximum air volume at node over the course of the transient simulation. Not applicable to Reservoirs and Rating curves.
Vapor Volume (Maximum, Transient): Maximum vapor volume at node over the course of the transient simulation. Not applicable to Reservoirs and Rating curves.
Speed (Maximum, Transient): Maximum turbine speed over the course of the transient simulation.
Speed (Minimum, Transient): Minimum turbine speed over the course of the transient simulation.
