Mechanical Properties of Fluids NCERT Solutions Class 11 Physics - Solved Exercise Question 10.12

Question 10.12:

Does it matter if one uses gauge instead of absolute pressures in applying Bernoulli’s equation? Explain.

Solution:
No
It does not matter if one uses gauge pressure instead of absolute pressure while applying Bernoulli’s equation. The two points where Bernoulli’s equation is applied should have significantly different atmospheric pressures.
