1.	Which of these equations are used to get the pressure values in the incompressible flows?(a) Continuity and momentum equations(b) Momentum and energy equations(c) Energy equation and equation of state(d) Equation of state and continuity equationsThe question was posed to me in an interview for internship.This intriguing question originated from Incompressible Flows in chapter Incompressible Flows & Compressible Flows of Computational Fluid Dynamics
Answer» The correct choice is (a) Continuity and MOMENTUM EQUATIONS Best EXPLANATION: The divergence of the momentum EQUATION is taken. The equation obtained from this is then simplified using the continuity equation to get the pressure values. So, a COMBINATION of continuity and momentum equations is needed here.
