The compressible flow is assumed to be ____

ক Adiabatic only
খ Isentropic only
গ Polytropic

সঠিক উত্তর: Isentropic only

Compressible flow is a branch of fluid mechanics that deals with different types of flow. Its main significance lies on the change in fluid density. It deals with gas dynamics. Flow is assumed to be isentropic.
