Q1.
Statement 1: Bernoulli’s equation can be applied to flow through pipes both, with and without friction.
Statement 2: Air is an incompressible fluid.
Discuss
Answer: (a).True, False
Discuss
Answer: (c).It is because the velocity in every layer varies and only the average velocity is accounted hence a correction factor is a need
