In the Bernoulli equation, i know that velocity is in m/s and mass in N which gives energy in joules. Likewise potential energy id also in joules being mgh. In pressure energy what are the variants? i.e what is formula for calcualting the pressure energy term in the equation? If we compute everything in joules, then how the pressure energy would be calculated? i want to know formula for calculating the pressure energy term in the equation.
