    V_infinty=98.772 m/s

    Explanation:

    complete question is:

    The following problem assume an inviscid, incompressible flow. Also, standard sea level density and pressure are 1.23kg/m3 (0.002377slug/ft3) and 1.01imes105N/m2 (2116lb/ft2), respectively. A Pitot tube on an airplane flying at standard sea level reads 1.07imes105N/m2. What is the velocity of the airplane?

    solution:

    given:

    p_o=1.07*10^5 N/m^2

    ρ_infinity=1.23 kg/m^2

    p_infinity=1.01*10^5 N/m^2

    p_o=p_infinity + (1/2) * (ρ_infinity) * V_infinty^2

    V_infinty^2=9756.097

    V_infinty=98.772 m/s
