-1 The SI unit of pressure is called the Pascal and has units of kg m s2. The pressure due to a column of fluid of height h depends on the height of the column, the density of the fluid, and the acceleration due to gravity. Thus, we can write this as: P = pa gb he where P is the pressure, p the density of the fluid, g is the acceleration due to gravity, and h is the height of the fluid column. Use dimensional analysis techniques to determine the values of a, b, and c, and thus the correct form of the pressure equation. intimnan
