Water Hammer
A Surge or " Water Hammer" in pipe or tube is a pressure spike caused by sudden variation of flow rate. and velocity energy is converted to pressure energy. Since the water flow is restricted inside a pipe, a shock wave will travel forth and back through the incompressible water in the pipeline deflecting everything in its path.

Kinetic Energy Calculator
Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2 .

SURGE CALCULATION
· Surge (or water hammer) is when you stop a liquid flow. The kinetic energy need to go somewhere. Why do you have to calculate: Because the surge pressure might exceed your design specs incl margins. But you dont _have_ to calculate anything. You may just hope that you have left the company if something goes wrong!

Water hammer
Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid in motion, usually a liquid but sometimes also a gas is forced to stop or change direction suddenly; a momentum change. This phenomenon commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe.
