Please compute the answer of the given question
Question- During a low-speed flight test, an airplane is equipped with some pressure gages in several locations. The test altitude is 8 km. Gage 1 indicates the pressure of 1550 N/m2 above the ambient pressure, while gage 2 shows the pressure of 3875 N/m2 below the ambient pressure.
Part A- If gage 1 is known to be at the stagnation point of the air flow, determine the airspeed and Mach number of the flight.
Part B- Determine the speed of the air near gage 2 relative to the airplane and relative to the ground, assuming no wind in the atmosphere.
Part C- What are the pressure coefficients at gage 1 and gage 2?
I need experts help to find the pressure coefficients at gage one.
