so ρgh is the gravitational potential energy per unit volume. Note that pressure P has units of energy per unit volume, too. Since P = F/A, its units are N/m2. If we multiply these by m/m, we obtain N ⋅ m/m3 = J/m3, or energy per unit volume. Bernoulli’s equation is...
Bernoulli's equation is essentially a more general and mathematical form of Bernoulli's principle that also takes into account changes in gravitational potential energy. We'll derive this equation in the next section, but before we do, let's take a look at Bernoulli's equation and get a feel...
and then annihilated close to the surface of Earth. Those photons would now have extra energy: not just theEfromE = mc2, but the additionalEfrom the amount of kinetic energy they gained by falling: from converting gravitational potential energy into the energy-of-motion...
However, recent calculations using numerical simulations of global ocean circulation have shown that the nonlinearity of the EoS leads to a sink of gravitational potential energy (PE), from which one might infer that there is less energy available to be released to the MOC. Here the available ...

Torricelli's theorem can be seen as a statement of the conservation of energy. When a particle of fluid with mass m falls a height h and reaches a speed v, its gravitational potential energy is converted to kinetic energy. Equating the formulas for the two forms of energy yields mgh=12mv2...
