Which one is steady flow compressor?
Reciprocating compressor
Define the term negative slip in reciprocating pump?
When the actual flow (Qa) is greater than theoretical flow (Qt) in a reciprocating pump it is negetive slip.
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.
How flow is continuous in single acting reciprocating pump?
momentum.
What is surge limit in cetrifugal compressor?
Surge Limit is the Minimum Flow Point ( in the compressor characteristic curve ) below which the compressor operation become instable. If the flow-rate is reduced, the pressure developed by the compressor decreases. Then, the pressure in the discharge line becomes greater , and the gas flow back into the compressor. As soon as the pressure in the discharge line drops to below that developed by the compressor, the gas again flows in the discharge line. Then, the cycle repeats. The oscillating pressure and flow rate will cause audible vibrations and shocks, and could damage the compressor blades, seals, and other components. Therefore, the compressor requires an antisurge control system to limit the flow rate at a minimum point, safely away from the surge limit.

Reciprocating compressor
What is relation between mass flow rate and discharge pressure in reciprocating compressor?
These have a inverse relation. You will need to know the discharge and the incoming pressure in order to find out the mass flow rate.
What does antisurge valve do in compressors?
The compressor antisurge valve opens to bypass flow from discharge to suction. This allows the compressor to flow through bypass and keeps the compressor from surging (reverse flow thru compressor). The discharge pressure does not continue to build due to closed discharge conditions.
What is stalling in compressor?
Damage of the blades of the compressor ,cauesd due high angles of pressure ,caused by air flow is called stalling of a compressor

What is the difference between a single acting reciprocating pump and a double acting reciprocating pump?
it runs without fluctuation i.r continuous flow......
What is surging in compressor?
Centrifugal and axial compressors will surge when forward flow through the compressor can no longer be maintained, due to an increase in pressure across the compressor, and a momentary flow reversal occurs. Once surge occurs, the reversal of flow reduces the discharge pressure or increases the suction pressure, thus allowing forward flow to resume again until the pressure rise again reaches the surge point. This surge cycle will continue until some change is made in the process or compressor conditions.
What causes the turbo charger surging?
If the turbo is too small, the turbo can go into surge, it is the part of the compressor map where the air flow is unstable. It is to the left on the compressor map, will cause damage if it taken care of.
What is negative slip in a reciprocating pump?
when actual flow(Qact) in pump is greater than theoretical flow (Qth) then negative slip occurs....
