How is bernoulli's equation derived
Web20 feb. 2011 · Let's use Bernoulli's equation to figure out what the flow through this pipe is. Let's just write it down: P1 plus rho gh1 plus 1/2 rho v1 squared is equal to P2 plus rho gh2 plus 1/2 rho v2 … Web26 aug. 2024 · Bernoulli’s equation is a form of the conservation of energy principle. Note that the second and third terms are the kinetic and potential energy with m replaced by ρ. In fact, each term in the equation has units of energy per unit volume. Here, (1/2)ρv 2 is the kinetic energy per unit volume.
