For low-speed (nearly incompressible) gas flow, the stagna-tion pressure can be computed from Bernoulli's equation:Po = P +pV²(a) For higher subsonic speeds, show that the isentropicrelation (9.28a) can be expanded in a power series asfollows:2 -kPo -p+ pv*(1+ Ma' +Ma' + --)24(b) Suppose that a pitot-static tube in air measures the pres-sure difference p, - p and uses the Bernoulli relation, withstagnation density, to estimate the gas velocity. At whatMach number will the error be 4 percent?

Assumption 1) Non-Viscous 2) Adiabatic 3) Isentropic 4) Steady flow
