ABSTRACT
The pressure head at B is 187*1 — 152-5 — 34*6 m and at E it is 178-8 — 149*0 - 29-8 m.
Contours of pressure are sketched in by interpolation.
6.6 Transient Behaviour 6.6.1 General Considerations In those cases of unsteady flow where the rate of change of discharge is appreciable the inertia of the water column can no longer be neglected
since significant pressures of a transient nature are developed. The phenomenon is known as water hammer and is so called because of the noise and vibration with which it is sometimes accompanied.
