The efficiency of the vane blower is (where W1 = Work done due to compression and W2 = Work done due to back flow)
A. $$\frac{{{{\text{W}}_1}}}{{{{\text{W}}_1} + {{\text{W}}_2}}}$$
B. $$\frac{{{{\text{W}}_2}}}{{{{\text{W}}_1} + {{\text{W}}_2}}}$$
C. $$\frac{{{{\text{W}}_1} + {{\text{W}}_2}}}{{{{\text{W}}_1}}}$$
D. $$\frac{{{{\text{W}}_1} + {{\text{W}}_2}}}{{{{\text{W}}_2}}}$$
Answer: Option B
Solution (By Examveda Team)
The efficiency of the vane blower is $$\frac{{{{\text{W}}_2}}}{{{{\text{W}}_1} + {{\text{W}}_2}}}$$Where,
W1 = Work done due to compression
W2 = Work done due to back flow
