Question
Bernoulli's Principle applies only in certain situations. The following situations are valid in using Bernoulli equation except:
Correct Answer
Option D is the correct answer.
Detailed Explanation
Bernoulli's equation applies to ideal fluid flow under specific conditions: the fluid must be incompressible, the flow must be steady, and the fluid must be non-viscous (without internal friction). All three conditions (i, ii, and iii) are necessary for Bernoulli's equation to be valid. Since the question asks for the exception (which situation is NOT valid), and all three are valid, option D correctly indicates that none are exceptions.
Hint
Bernoulli's equation applies to ideal fluids: incompressible, steady flow, and non-viscous.
