Why will a vacuum pump not operate for a well that is deeper than 10.3 m?
The reason behind the vacuum pump to not operate for a well that is deeper than 10.3 m.
Explanation of Solution
Introduction:
Liquid pressure increases with increase in depth of a liquid. An atmospheric pressure is due to weight of the air.
Beyond depth of 10.3 m, value of water pressure is same as that of atmospheric pressure. There is no pressure difference. Due to this, no force is there to lift the water up. So vacuum pump does not operate in a well that is deeper than 10.3 m.
Conclusion:
After 10.3 m depth the water pressure and atmospheric pressure are same.
