Consider a large rain water tank for a remote farmhouse. The farmhouse occupants are constantly concerned with the amount of water in the tank and adjust their water needs based upon this water. The cross-sectional area of the vertical sided tank is A. Suppose that the "ran off' from the house gutters goes into the tank and has a time dependent volumetric flow of R. Suppose a "demand driven" pump supplies water from the tank to the house for domestic puiposes at a time dependent flow rate of W. There is an old tap on the bottom of the tank which is no longer used. However, this tap is corroded and cannot be completely turn off so there is a small trickle of water constantly coming out of the tap. A student has suggested modelling this trickle rate T as being proportional to the amount of water in the tank. Develop a model of the height H of water in the tank to the various flow rates and parameters in the system. What are the MV PV and DV for this system? Develop the transfer functions of the system relating the MV to the PV and the DV to the PV. Draw a block diagram of the overall system. What changes in the system if any. are there if the water is pumped out of the system at a constant rate?
