The physical property Φof the general transport equation is replaced by ________ to get momentum equation.(a) Velocity vector(b) Mass(c) Force vector(d) Acceleration vectorThe question was asked in an international level competition.The doubt is from Momentum Equation in chapter Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer»

The CORRECT OPTION is (a) Velocity vector

Best explanation: The physical property in general transport equation should be REPLACED by velocity vector. This will result in momentum equation. For mass CONSERVATION, Φ = 1. For momentum (mass×velocity) conservation, Φ = 1×\(\vec{V}=\vec{V}\).
