What is the significance of specific speed?
Specific speed (Ns) is a non-dimensional design index used to classify pump impellers as to their type and proportions. It is defined as the speed in revolutions per minite at which a geometrically similar impeller would operate if it were of such a size as to deliver one gallon per minute against one foot of head. The formula used to determine specific speed is Where N = Speed of Pump in RPM Q = Capacity in gpm at the best efficiency point H = Head per stage in feet at the best efficiency point The specific speed determines the general shape or class of the impeller. As the specific speed increases, the ratio of the impeller outlet diameter, D2, to the inlet or eye diameter, Di, decreases. This ratio becomes 1.0 for a true axial flow impeller. Low specific speed - Radial flow Impeller. Medium specific speed - Mixed flow Impeller. High specific speed - Axial Flow Impeller.
Should i run my pool pump on high or low speed?
High for extreme use, low for little use.
How fast should you drive in high wind conditions?
You should adjust your speed to a reasonable and safe speed. There is no specific number attributed to it.

How works water pump?
A water pump is very simple the pump is turned by the serpentine belt. The inside of the pump isn't anything more than fins that move the water at a high rate of speed that varies on the rpms of the car.
Is it possible to without changing pump speed liquid can be pumped at high pressure?
change to a smaller size line from the pump will increase the pressure the volume will stay constant.
What are some common questions about pool pumps?
How much water does it pump over a given period of time. Does it need priming when empty. Is it a high head pump. i.e. how far will it lift water. Is this a two speed pump or the normal single speed. does it have an automatic cut of in case of over heating.
What has the author W Fro ssel written?
W. Fro ssel has written: 'High-speed lubricating oil pump'
If you double the speed of centrifugal pump?
Centrifugal pumps generally obey what are known as the pump laws. These laws state that the flow rate or capacity is directly proportional to the pump speed; the discharge head is directly proportional to the square of the pump speed; and the power required by the pump motor is directly proportional to the cube of the pump speed.
Why is your 2004 explorer making a humming sound when you accelerate to a high speed only humming when on the gas pedal?
Check your fuel pump
What are the advantages of induction motor?
1. Induction motor has high starting torque, therefore use for operate pump which need high starting torque. 2. Induction motor operate on variable speed. 3. It can be used as generator when speed of motor is higher than synchronous speed.
