Is the velocity in parallel pipes the same as a single pipe according to Bernoulli's equation?
This system pushes water through a nozzle. I can use Modified Bernoulli's equation to calculate the nozzle velocity as such:
$$V_3 = \sqrt{2g\left(\frac{P_1}{\rho g}+ z_1-\Delta h_L\right)}$$
where ($\...
