A municipal water distribution system experiences fluctuating demand; which effect results when the system of linear equations representing water flow and pressure at each node becomes underdetermined?

💡 Explanation

An underdetermined system has more unknowns than equations, therefore it has infinitely many solutions; this stems from the mechanism of linear dependence within the matrix representing the system. Because the flow rates are not uniquely defined, there are many possible solutions, rather than a single or inconsistent one.
