Exercise 1. 'Water
in bathtub' is the stock, measured as a volume of water, in L. The bath is initially empty. The bath receives water from the taps ('Variable inflow from tap', in
L/min) and loses water to the drain ('Constant outflow to drain', in
L/min). 'Twiddling the taps' automatically switches the inflow from 40
L/min to 20 L/min at 5 minute (300 second) intervals. The outflow
remains constant at 30 L/min.

Exercise 2. 'Water
in bathtub' is the stock, measured as a volume of water, in L. The bath initally holds 100 L of water. The bath receives water from the taps ('Variable inflow
from tap', in
L/min) and loses water to the drain ('Constant outflow to drain', in
L/min). 'Twiddling the taps' gradually ramps the inflow between a minumum of 0
L/min and a maximum of 60 L/min within each 5 minute (300 second) intervals. The outflow
remains constant at 30 L/min.

This model fills a bathtub, while outflow occurs at a flow determined by the volume of water (or pressure at outlet) of the bathtub. It could just as well be a dam or lake that is modeled.

Negative Feedback Structure With Positive Goal
Exercise 2. The bath initially holds 100 L of water. Water flows in through the tap at a variable rate (L/min) and flows out through the drain at a constant rate (30 L/min). Control of the tap is pre-set.
