The efficiency of the vane blower is (where W₁ = Workdone due to compression, and W₂ = Workdone due to back flow)

W₁/(W₁ + W₂)

W₂/(W₁ + W₂)

(W₁ + W₂)/W₁

(W₁ + W₂)/W₂

Answer : Option B

Explanation :

The efficiency of the vane blower is W₂/(W₁ + W₂) where, W₁ = Workdone due to compression W₂ = Workdone due to back flow
