Accurately calculating the pressure drop through an orifice

[QUOTE="gtoguy97, post: 6896834, member: 514117"] The easiest way to calculate the pressure drop across a nozzle is to use the Bernoulli equation. The Bernoulli equation states that the sum of the potential energy and kinetic energy of the fluid is constant. This means that if you know the inlet pressure, outlet pressure, and velocity of the fluid at both the inlet and outlet, you can calculate the pressure drop across the nozzle.Assuming you have all of the necessary information, the pressure drop across the nozzle can be calculated with the following equation:Pressure Drop = (Inlet Pressure) - (Outlet Pressure) + (1/2)*(Inlet Velocity^2 - Outlet Velocity^2)In this case, since you know the flow rate, you can use the equation for flow rate to calculate the velocities at both the inlet and outlet. Once you have those values, you can substitute them into the Bernoulli equation to calculate the pressure drop. [/QUOTE]
