Will the height of the water column change if the cross section of the water column is made wider ?

Text Solution

AI Generated Solution

To determine whether the height of a water column changes when the cross-section of the column is made wider, we can analyze the situation step by step. ### Step 1: Understand the Relationship Between Pressure and Height The pressure at a certain depth in a fluid is given by the formula: \[ P = \rho \cdot g \cdot h \] where: - \( P \) = pressure, - \( \rho \) = density of the liquid, ...
