Compressors-Chapter 7

What is the primary advantage of positive displacement compressors over dynamic compressors?

• Higher efficiency
• Higher capacity
• More expensive
• More maintenance

What factor should be considered when selecting a type of compressor?

• Viscosity
• Discharge pressure
• Type of liquid being compressed
• All of the above

What is a critical factor to consider when selecting a compressor for a specific application?

• Color of the compressor
• Weight of the compressor
• Discharge pressure
• Brand of the compressor

How does the flow rate affect the choice of compressor?

• Higher flow rate requires a larger compressor
• Flow rate only affects the color of the compressor
• It has no impact on the choice
• Higher flow rate requires a smaller compressor

Which type of compressor is more suitable for applications where a continuous flow of gas is required?

• Axial compressor
• Centrifugal compressor
• Reciprocating compressor
• Rotary compressor

What is the primary disadvantage of positive displacement compressors compared to dynamic compressors?

• Less expensive
• Higher efficiency
• Higher capacity
• More maintenance

Which type of compressor is best suited for applications requiring high pressure but low flow rates?

• Axial compressor
• Centrifugal compressor
• Rotary compressor
• Reciprocating compressor

Which of the following is NOT a factor to consider when selecting a compressor?

• Color of the compressor
• Discharge pressure
• Flow rate
• Type of gas being compressed

How is flow rate expressed?

• Pounds per square inch (psi)
• Milliliters per second (mps)
• Kilopascals (kPa)
• Cubic feet per minute (cfm)

Why are dynamic compressors more commonly used than positive displacement compressors?

• They have a smaller capacity
• Multiple fuel types can be utilized
• They are more sophisticated
• They require less maintenance
