A Pump for the Tank

Problem Statement:

Figure 2 shows the same tank as Figure 1, but with a pump into the system with a constant, configurable volumetric flow rate of V_in (gal/s). The pump contains an on-off switch. Reconfigure the model to include the pump and manually tune the system to hold a constant water level. Use FLNKs to trigger processing of records.

Update your PyDM display with the following:

• Inlet Pump Status
• Control input for pump flow rate
• Control input for pump on-off switch
