The flows in which all the flow parameters are the function of ‘x’

1.	The flows in which all the flow parameters are the function of ‘x’ is called as _________(a) 3D flow(b) 2D flow(c) Quasi 1D flow(d) Quasi 2D flowThe question was posed to me by my college director while I was bunking the class.This intriguing question comes from Incompressible Flow in Duct topic in chapter Inviscid & Incompressible Flow of Aerodynamics
Answer» Correct answer is (c) Quasi 1D flow The explanation: GENERALLY, the flow field properties are UNIFORM across any cross section and hence, they vary only in x-DIRECTION. All the flow parameters are assumed to be the function of x. A=A(x), V=V(x), p=p(x) and SINCE they vary only in one direction they are called quasi 1D flow.
