When deriving the isentropic flow equations, the common assumptions made include:
1. **q=0**: This implies that there is no heat transfer to or from the fluid, meaning the process is adiabatic.
2. **No frictional effects**: This means that the flow is assumed to be inviscid, or frictionless, which allows us to neglect viscous effects that can cause energy losses.
3. **No dissipative effects**: This further reinforces the idea that there are no losses due to non-conservative forces (like friction or turbulence).
Given these points, the correct answer to your question is:
**All of the above.**
These assumptions are critical for the simplifications in deriving the isentropic flow equations, which describe idealized flows without energy loss.
