1. The Two-Tank experiment in the senior PDC Lab can be operated in the following manner
W2
W1
h1
h2
W3
W4
a) Develop a model for the two-tank system that can be used to find h1, h2, W3 and w4 as functions of time
for any given variations in the inputs.
b) Perform a degrees of freedom analysis. Identify all input and output variables as well as all model
constants.
Note the following assumptions can be made:
The density of water is constant.
The flow between tanks w3 is positive for flow from Tank 1 to Tank 2.
All valves are linear with resistances k3 and k, (i.e., W= k*AP where AP is the pressure drop across
the valve)
