1.	According to Euler’s equation, what happens to the velocity of the inviscid flow if the pressure increases?(a) No change(b) Increases(c) Decreases(d) Becomes zeroI have been asked this question by my school teacher while I was bunking the class.I need to ask this question from Irrotational Flow in chapter Velocity Potential Equation of Aerodynamics
Answer» RIGHT option is (c) Decreases Best EXPLANATION: ACCORDING to the EULER, the RELATION between velocity and pressure for an inviscid fluid is given by dp = – ρVdV. According to the relation, due to the presence of negative sign, when the pressure increases velocity decreases and vice versa. The same concept is also explained using Bernoulli’s principle.
