Bernoulli Equation Examples

For reference, the Bernoulli equation is: $latex E_t = E_p + E_v + E_z\newline \indent =\frac{p}{\rho}+\frac{v^{2}}{2}+zg\hspace{20px}^{(SI)}\newline \indent =\frac{p}{\rho}+\frac{v^{2}}{2g_c}+\frac{zg}{g_c}\hspace{20px}^{(US)}&s=2$ Example 1 A reservoir contains an outlet that consists of a pipe that discharges water 50 ft below the top of the reservoir. What is the velocity of the water exiting the pipe (at point B)? Solution […]

How to Use the Bernoulli Equation

The Bernoulli equation states that the total energy possessed by a fluid is the sum of its pressure, kinetic, and potential energies. $latex E_t = E_p + E_v + E_z\newline \indent =\frac{p}{\rho}+\frac{v^{2}}{2}+zg\hspace{20px}^{(SI)}\newline \indent =\frac{p}{\rho}+\frac{v^{2}}{2g_c}+\frac{zg}{g_c}\hspace{20px}^{(US)}&s=2$ Using this starting point, we can calculate the total head, ht, and total pressure, pt, that the fluid is under: $latex […]
