6. D2 In terms of stagnation variables, We assume choked flow, so that M = l ~~ v~---- y (l+y ) -yy+l - T("y-T) We assume an adiabatic process, so that = P:}y~l T y-1 y For a small leak rate (no shocks in hull atmosphere), stagnation conditions hold throughout the hull. Then Vol Rmix Y-1 Pi -y- l- y-l -T-.-- Po y l.
