From an initial design point of view, engineers often use a quantity termed the specific speed to identify the most suitable pump type for a particular combination of flow rate and head.

Axial fans operate at high specific speed i . e ., high flow rate and low head and hence adding more blades will restrict the high flow rate required for its operation.
43.
For increased safety, each vehicle is also fitted with an automatic brake that is triggered if the vehicle exceeds a specific speed, such as a carriage running away or a locomotive engine failure.
44.
A six-way power seat was a new option, as was " Speedminder ", for the driver to set a needle at a specific speed and a buzzer would sound if the pre-set was exceeded.
45.
In applications which stay relatively in the atmosphere and require longer durations of lower thrust over a specific speed range the air turborocket can have a weight advantage over the standard solid fuel rocket motor.
46.
Increasing the number of jets increases the specific speed of the runner by the square root of the number of jets ( four jets yield twice the specific speed of one jet on the same turbine ).

48.
The act does not stipulate a specific speed for the simulated noise but requires the U . S . Department of Transportation to study and establish a motor vehicle safety standard that would set requirements for an alert sound.

This implies that the Specific speed ( N s ) on which Kaplan turbine functions is high as Specific speed ( N sp ) is directly proportional to Flow ( Q ) and inversely proportional to Head ( H ).
