Compared to other turbine designs, the relatively low specific speed of the Pelton wheel, implies that the geometry is inherently a " low gear " design.
32.
Backward curved fans can have a high range of specific speeds but are most often used for medium specific speed applications high pressure, medium flow applications.
33.
The specific speed of a turbine is given by the manufacturer ( along with other ratings ) and will always refer to the point of maximum efficiency.
34.
The frames are later played back in a cin?projector at a specific speed, called the " frame rate " ( number of frames per second ).
35.
The frames are later played back in a movie projector at a specific speed, called the " frame rate " ( number of frames per second ).
36.
Specific speed is an index used to predict desired pump or turbine performance . i . e . it predicts the general shape of a pumps impeller.
37.
Compressor stages run at their maximum efficiency when spinning at a specific speed for any given input air pressure-in a perfect compressor each stage would run at a separate speed.
38.
A " prima facie " speed limit is a default speed limit that applies when no other specific speed limit is posted, and which may be exceeded by a driver.
39.
The specific speed value for a turbine is the speed of a geometrically similar turbine which would produce unit power ( one kilowatt ) under unit head ( one meter ).
40.
Pump specific speed can be calculated using British gallons or using Metric units ( m 3 / s or L / s and metres head ), changing the values listed above.
