To determine which conditions will NOT affect the pressure of fluids, we use the formula for hydrostatic pressure:
$$P = \rho g h$$
where:
• $P$ is the pressure
• $\rho$ (rho) is the density of the fluid
• $g$ is the acceleration due to gravity
• $h$ is the depth of the fluid
Let's analyze each condition:
I. Density of the liquid ($\rho$): From the formula, pressure is directly proportional to the density of the liquid. Therefore, the density of the liquid will affect* the pressure.
II. Acceleration due to gravity ($g$): Pressure is directly proportional to the acceleration due to gravity. Therefore, acceleration due to gravity will affect*
