Answer:
An aircraft flying at sea level with a speed of 220 m/s, has a highest pressure of 29136.8 N/m²
Explanation:
Applying Bernoulli's equation, we determine the highest pressure on the aircraft.
[tex]P = \frac{1}{2} \rho V^2[/tex]
where;
P is the highest pressure on the aircraft
[tex]\rho[/tex] is the density of air = 1.204 kg/m³ at sea level temperature.
V is the velocity of the aircraft = 220 m/s
P = 0.5*1.204*(220)² = 29136.8 N/m²
Therefore, an aircraft flying at sea level with a speed of 220 m/s, has a highest pressure of 29136.8 N/m²
Answer:
highest pressure = 101325 + 29524 = 130849 Pa
Explanation:
the highest pressure that can act at the sea level is the sum of dynamic pressure (due to flowing fluid) and the static pressure (due to stationary fluid).
P =P_static + P-dynamic
P_static = 1 atm = 101325 Pa
P_dynamic = 0.5*p*v^2
where p: density of fluid = 1.22 kg/m^3 at sea level
v: fluid velocity = 220m/s
P_dynamic = 0.5 * 1.22*220^2 = 29524 Pa
highest pressure = 101325 + 29524 = 130849 Pa
