What is water hammer? Water hammer (or hydraulic shock) is themomentary increase in pressure, which occursin a water system when there is a suddenchange of direction or velocity of the water.When a rapidly closed valve suddenly stopswater flowing in a pipeline, pressure energy istransferred to the valve and pipe wall.ater hammer (or hydraulic shock) is themomentary increase in pressure, which occursin a water system when there is a suddenchange of direction or velocity of the water.When a rapidly closed valve suddenly stopswater flowing in a pipeline, pressure energy istransferred to the valve and pipe wall.
Though both AC and DC currents and shock are lethal, more DC current is required to have the same effect as AC current. For example, if you are being electrocuted or shocked 0.5 to 1.5 milliamps of AC 60 Hz current is required and up to 4 mA of DC current is required.
