WebHead is expressed in units of distance such as meters or feet. The force per unit volume on a fluid in a gravitational field is equal to ρg where ρ is the density of the fluid, and g is the gravitational acceleration. WebThe formula to compute the water pressure is P = ρ * g * h. Where ρ is the density of water, g is the gravitational constant and h is the height. The constant value of water density is 997 kg/m³, gravitational constant is 9.81 m s -2. Substitute the values in the formula. Perform multiplication of those 3 numbers to get the answer. busyhands spa
