Vacuum efficiency is given by:
\( \text{Vacuum Efficiency} = \frac{\text{Actual Vacuum}}{\text{Ideal Vacuum}} \times 100 \)
Given:
- Barometer reading = 760 mm Hg
- Vacuum recorded in condenser = 690 mm Hg
- Saturation pressure at 35°C = 42.21 mm Hg
Calculation:
Ideal Vacuum = \( 760 - 42.21 = 717.79 \, \text{mm Hg} \)
Vacuum Efficiency = \( \frac{690}{717.79} \times 100 = 96.10\% \)
