Question

If in a reciprocating compressor the volume of compressed air per hour is 72.5 m3/hr. If the volumetric efficiency of the compressor was 84%, then what is the actual volume compressed?

A) 46.5 m3/hr.
B) 51.8 m3/hr.
C) 60.9 m3/hr.
D) 65.6 m3/hr.
E) 68.3 m3/hr.

Answer 1

The actual volume compressed by the reciprocating compressor with a volumetric efficiency of 84% and a rated volume of 72.5 m3/hr is 60.9 m3/hr.

Step-by-step explanation:

To find the actual volume compressed, we need to divide the given volume of compressed air per hour by the volumetric efficiency of the compressor. The volumetric efficiency is expressed as a percentage, so we need to convert it to a decimal by dividing it by 100. To calculate the actual volume compressed:

If a reciprocating compressor has a volume of compressed air per hour at 72.5 m3/hr and a volumetric efficiency of 84%, the actual volume compressed can be calculated by multiplying the total volume by the efficiency. Therefore, the actual volume compressed is 72.5 m3/hr × 0.84 = 60.9 m3/hr.
