Consider the cross-section of wing
Similar to previous question
Also, p1 = 9 × 104 Pa [for away point in atmosphere] V1 = 720 km/hr V1 = 200 m/sec y1 = y2
V2 = 0
Substituting these conditions in the Bernoulli’s equation
∴ p2 = 112 kPa

Given data:
Speed of the plane (V) = 720 km/hr = 200 m/s
Altitude (h) = 1000 m
Pair = 9.0 × 10^4 N/m^2
Density (ρ) = 1.1 kg/m^3

Calculating the absolute stagnation pressure:
To calculate the absolute stagnation pressure at the leading edge of the wing, we can use the formula:
P0 = Pair + 0.5 * ρ * V^2

Substitute the given values:
P0 = 9.0 × 10^4 + 0.5 * 1.1 * (200)^2
P0 = 9.0 × 10^4 + 0.5 * 1.1 * 40000
P0 = 9.0 × 10^4 + 0.5 * 44000
P0 = 9.0 × 10^4 + 22000
P0 = 112000 N/m^2
Therefore, the absolute stagnation pressure at the leading edge of the wing is 112 kPa. Hence, the correct answer is option C.
