What is the difference between centrifugal compressor and screw compressors?
A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.
Why do pumps burn up when it runs dry?
Friction of the mechanical seal faces running together without lubrication or the shaft packing running against the shaft without cooling by water seepage are the result of pumps running dry. Impeller clearances are usually wide enough that the impeller and volute aren't damaged when dry running occurs, but if the pump uses the fluid media to maintain a balance or if tolerances are extremely tight and there is contact with the impeller and volute then galling, damaging, and possibly seizing the impeller could happen.

What is a turbo in the pt cruiser?
It is a turbo charger. A turbo charger uses exhaust gases to turn an impeller that is attached to a shaft and another impeller that forces more air into the intake system of the engine. This increases power and engine efficiency.
What are the uses of micrometer screw gauge?
mafanta
What uses the flow of exhaust gasses out of the engine to pressurize the air entering the intake manifold?
a turbocharger uses exhaust gas to spin an impeller that boost atmospheric pressure and feeds it into engine
What are the uses in construction for a ball screw jack?
There are several uses for a balll screw jack. Ball screw jack assemblies use small balls to roll between the nut and the lifting ball screw. It creates less friction and increases use life.
