Which of the following assumptions is true in case of GVF?
(a) The flow is not steady
(b) The streamlines are parallel
(c) Pressure distribution is not hydrostatic
(d) Channel has varying alignment and shape
This question was posed to me by my college professor while I was bunking the class.
This key question is from Gradually Varied Flow(GVF) topic in chapter Non Uniform Flow in Channels of Fluid Mechanics
