Bernoulli's equation for fluid flow is derived following certain assumptions. Out of the assumptions listed below, which set of assumptions is used in derivation of Bernoulli's equation ?
1. Fluid flow is frictionless & irrotational.
2. Fluid flow is steady.
3. Fluid flow is uniform & turbulent.
4. Fluid is compressible.
5. Fluid is incompressible. - For turbulent flow of an incompressible fluid through a pipe, the flow rate Q is proportional to (Δ P)n, where ΔP is the pressure drop. The value of exponent 'n' is
