Question: a for a steady inviscid and adiabtaic flow the stagnation...

Question details

a) For a steady, inviscid, and adiabtaic flow, the stagnation enthalpy is constant along a streamline, i.e ho = h +-= const. If the flow is also a perfect gas, use this enthalpy relation to derive the compressible form of Bernoullis equation = const. b) Derive the same compressible Bernoulli equation obtained in eq. (2) using only the conservation of mass and momentum. To do this, first show that for steady flow in a duct of constant area: dp + udu = 0 This is obtained by letting u-u, Pi, pp, and u-u + du, p2-p + dp, Pa-ρ+ dp. Then, by assuming isentropic flow, make use of the relation for p/p (Hint: substitute for ρ) then integrating eq. (3) c) Starting with eq. (3) derive an alternate compressible Bernoulli equation if the flow is isothermal instead of isentropic, i.e. p/,-RT-C
