State Quantities

nThe
initial height *h**1** *and cross sectional area A are both state
quantities. They are algebraically
combined with the path quantity Vno drainage to give the state quantity *h**2**.
*Notice that the path quantity Vno drainage must be well defined by
specifying that there is no drainage. This careful description
is necessary for the equation in the last slide to be valid.
