Gas Turbine Engineering Handbook
221 Thus, the area distribution at any section 6 can be given by the following
relationship: A9 : Qr x — x — (6-14) 21 where r : radius to the center of gravity L :
volume width Second, design the volute by assuming that the pressure and
velocity ...

Centrifugal Pump Design
volute throat and the exit flange, depending on the available space and the flow
velocities. The gradually increasing volute flow cross sections are calculated from
the flow rate and from an average velocity at the volute cross section center.
3
Fundamentals of Turbomachinery
Sometimes the volute also serves as a diffuser or is followed with a conical
diffuser. A vaned diffuser immediately downstream of the impeller can improve
efficiency, but it tends to limit the stable operating range. Because the flow
discharged ...

Process Centrifugal Compressors: Basics, Function, ...
Since the volute flow regime is still governed by the law of conservation of
angular momentum, the external volute achieves a static pressure increase and a
smaller loss through a lower velocity level at the price of a larger outer diameter.

Basic Mechanical Maintenance Procedures at Water and ...
A centrifugal pump consists of a rotating element (impeller) sealed in a casing (
volute). The impeller is connected to a drive unit that supplies the energy to turn it
. As the impeller turns inside the volute casing, an area of low pressure is created
...
Using a bull's-eye level to check for level, I again set the volute atop the newel
and the newel on the tread, but behind its hole. 1 rotate the volute so that its up-
easing parallels the rail. With the rail and volute lined up, I can eyeball them from
...

Fluid Dynamics of Cavitation and Cavitating Turbopumps
Typical non-cavitating performance for a centrifugal pump, namely Impeller X (
see section 3.8) with Volute A and a circular volute of uniform cross-section (from
Chamieh 1983). it performs reasonably well down to about 30% of this design
flow ...

where the pump casing has to accommodate several impeller sizes; where pump
has to use a fabricated casing; where volute passage has to be machined from a
casting; where foundry limitations result in higher impeller width.

Introduction to Fire Pump Operations
volute. an increasing void space in a pump that converts velocity into pressure
and directs water from the impeller to the discharge The impeller is typically
mounted eccentric to the pump casing. The void space created by this design is
called ...

Fluid Machinery: Performance, Analysis, and Design
and a radius characteristic of the volute is given as r^ The volute radius is a
function of the angular position in the volute and is usually linear between the
volute "entrance and exit." The entrance/exit points as seen in Figure 7.37 relate
to the ...
