Question

single stage Screw compressors have the capability to operate at pressure ratios above –

a.
none of the above

b.
20:1

c.
10:1

d.
50:1​

Answer 1

Answer:

The turndown capability using variable volume pockets is less than using the slide valve in the screw compressor. Screw compressors can operate from roughly 2 to 20 ratios of compression on a single stage while maintaining high volumetric efficiencies.
