Why are dynamic compressors more commonly used than positive-displacement compressors?
A) They have a smaller capacity
B) They are more readily available
C) They require less maintenance
D) They are more expensive
Answer: C
Explanation: A) Incorrect. Dynamic compressors are more commonly used than positive-displacement compressors because they have a larger capacity and require less maintenance. They also can be less expensive and more efficient, depending on the service application.
B) Incorrect. Dynamic compressors are more commonly used than positive-displacement compressors because they have a larger capacity and require less maintenance. They also can be less expensive and more efficient, depending on the service application.
