What are the disadvantages of insulators?
One disadvantage of a insulator is that it will not let current flow if you need it to. By the same token one advantage of an insulator is that it will not let current flow if it tries to.
Which one is steady flow compressor?
Reciprocating compressor
What are disadvantages and advantages of turbulent flow?
Advantage: objects in a turbulent flow experience less drag. Disadvantage: turbulent flows are unstable meaning velocity and pressures change rapidly. The objects in the flow have less stability. The flow also is more difficult to model then a laminar flow.
What is a advantage and disadvantage conductors of electricity?
An advantage of conductors of electricity is that they allow the flow of electric current, making them essential for creating electrical circuits and transmitting electricity. A disadvantage is that they can also present a safety hazard if not properly insulated or if the current flowing through them is too high, leading to potential electric shock or overheating.
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.
How do you calculate surge in compressor?
To calculate surge in a compressor, you would need to determine the maximum flow rate and pressure that the compressor can handle without stalling. This can be done through performance mapping or testing. Surge is typically defined as the flow rate at which the compressor stalls due to flow reversal.
What is the function of the air conditioning compressor contactor in regulating the flow of electricity to the compressor unit?
The air conditioning compressor contactor controls the flow of electricity to the compressor unit, allowing it to turn on and off as needed to regulate the temperature in the air conditioning system.
The frontal area of a centrifugal compressor as compared to axial flow compressor is larger or smaller?
the frontal area of a centrifugal compresor is more as compared to axial flow compressor for a given air flow. And for this reason axial compressors are being used in aircraft engines.
An Advantage and Disadvantage for steam system thnxs?
Steam has the capacity to flow through the system without support of external energy sources like pumps. However, it lacks modulating quality
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 Advantage and dis advantage of flow chart?
What is the Advantage and dis advantage of TCP/IP
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.
