Pressure due to the weight of a liquid of constant density is given by p = \rhogh, where p is the pressure, h is the depth of the liquid, \rho is the density of the liquid, and g is the accele...Pressure due to the weight of a liquid of constant density is given by p = \rhogh, where p is the pressure, h is the depth of the liquid, \rho is the density of the liquid, and g is the acceleration due to gravity. Bernoulli’s equation states that the sum on each side of the following equation is constant, or the same at any two points in an incompressible frictionless fluid: $p_{1} + \frac{1}{2} \rho v_{1}^{2} + \rho gh_{1} = p_{2}+ \frac{1}{2} \rho v_{2}^{2} + \rho gh_{2} \ldotp$
