Q. With increase in molecular weight of gas, the head developed by a centrifugal compressor will:

गैस के आणविक भार में वृद्धि के साथ, एक केन्द्रापसारक कंप्रेसर द्वारा विकसित सिर होगा:

A
Decrease
घटाना
B
Increase
बढ़ोतरी
C
Remain same
वही रहो
D
Unpredictable
अप्रत्याशित

Explanation

The head developed by a centrifugal compressor depends inversely on the molecular weight of the gas. Heavier gases require more work to achieve the same velocity increase, thus reducing the head for the same energy input.
