Practical Hydraulics Handbook, Second Edition
The formula for Velocity Head calculation is: Velocity Head = 2 x gravity 2g 64.4
For derivation see Appendix IV. Note: Velocity Head, when used in calculations is
always registered as feet of water. In a pressurized pipe system, Velocity Head ...

11.2.5 veloCity head Velocity head is the amount of head or energy required to
maintain a stated velocity in the suction and discharge lines. The design of most
pumps makes the total velocity head for the pumping system zero. Note: Velocity
...
When dealing with flow through pipes and open channels, we must also consider
velocity head. The velocity head in soils, however, is much too small to be of any
consequence and thus can be neglected. (For example, a high velocity for fluid ...

Hydraulics for Operators
The same applies to water which has kinetic energy because of its velocity:
Velocity Head. It is the distance which the water can move due to velocity energy.
Like Pressure Head and Elevation Head, Velocity Head is also expressed in feet
of ...

Process Plant Machinery, Second Edition
It is dependent upon the size and type of pipe, flow rate, and nature of the liquid.
VELOCITY HEAD (hv) is the energy of a liquid as a result of its motion at some
velocity V. It is the equivalent head in feet through which the water would have to
...

Operation Of Fire Protection Systems
Normal atmospheric pressure is taken as 14.7 psi ( 101 .4 kPa), equivalent to a
head of water of 33.95 ft (10.35 m) and a head of mercury of 29.9 in. (760 mm).
Velocity Head or Velocity Pressure. The velocity, u, produced in a mass of water
by ...

(d) the centre line of the pipe can never be above the energy line 4.5 The total
head in a flow is the sum of (a) piezometric head and datum head (b) piezometric
head and pressure head (c) piezometric head and velocity head (d) piezometric ...

Fundamentals of Hydraulic Dredging
The simple physical concept of velocity head is that it is the feet of head required
to produce a given velocity. In the example above, 4 feet of head is required to
produce a velocity of 16 feet per second. Doubling the head available will not ...

10.2.5 velocity head velocity head is the amount of head or energy required to
maintain a stated velocity in the suction and discharge lines. The design of most
pumps makes the total velocity head for the pumping system zero. Note: Velocity

Pump Characteristics and Applications, Third Edition
The velocity head (see Section III.D below) is taken at the points of the gauge
connec— tions, and the friction head (see Section III.B above) is only the friction
losses between the two gauges. D. Velocity Head Velocity head is the energy of
a ...
