| The pump curve describes how a centrifugal pump performs in isolation from plant equipment | 78 snail Vitesse d'un escargot Speed of a snail |
|---|---|
| KTAS is "knots ", the airspeed of an aircraft relative to undisturbed air | Ideally, the operating point and best efficiency points should coincide |
What is Suction Specific Speed? At the other end of the scale, axial flow impellers are preferred if the specific speed is greater than 175 US units: 9000.
| This can lead to cavitation, vibration and seal wear | How is Specific Speed calculated? Specific Speed is an important factor in the design and selection of pumps and especially pump impellers |
|---|---|
| , which deals with theoretical estimates of practical maximum speed of displacement hulls | For a particular pump design, the performance can be modified by fitting a different impeller, by operating it at a different rotational speed, or by changing the suction side pipe diameter |
KIAS is "knots ", the speed shown on an aircraft's.
| KTAS is "knots ", the airspeed of an aircraft relative to undisturbed air | KEAS is "knots ", the calibrated airspeed corrected for for the particular altitude |
