Answer to Question #229827 in Mechanical Engineering for Zillur Rahman

Question

Can u let me if any screw compressor discharge pressure is 2 bar then how much compressor capacity approximately.

Answer 1

compressor capacity :

$A = Q.\frac{\beta}{\eta}=$

$Q =238.48 \frac{l}{min}$

$\beta = 1.3$

$\eta = 0.75$

$A = Q.\frac{\beta}{\eta}= 283.48 \frac{1.3}{0.75}= 491.36 \frac{l}{min}$

where

Q – total air volume to be consumed by all consumers of pneumatic system to be measured in l/min;

β – coefficient to count for design specifics of compressor unit by manufacturer;

η – performance index of compressor unit.
