An oblique shock is inclined at an angle of 35 degrees to the upstream flow of

velocity $517.56 \mathrm{~m} / \mathrm{s}$. The deflection of the flow due to this shock is 5.75 degrees and the temperature downstream is $182.46 \mathrm{~K}$. Assume the gas constant $R=287 \mathrm{~J} /(\mathrm{kg} \mathrm{K})$, specific heat ratio $\gamma=1.4,$ and specific heat at constant pressure $C_{p}=1005 \mathrm{~J} /(\mathrm{kg} \mathrm{K})$ Using conservation relations, the Mach number of the upstream flow can be

obtained as $\quad$____________ (round off to one decimal place).
