hi all, am a confused-being after trying to solve this really simple question.. somewhere somehow my concepts are just not right ): Consider an airplane flying with a velocity of 60m/s at a standard altitude of 3km. At a point on the wing, the airflow velocity is 70m/s. Calculate the pressure at this point. By using p1+1/2(rou)(v1)^2=p2+1/2(rou)(v2)^2 and the standard atmospheric pressure table, the given solution is 7.0121 X 10^4 + 1/2(9.0926X10^(-1))(60^2)/2 = P2 + 9.0926X10^(-1)(70^2)/2 I do not understand why P1 = 7.0121 x 10^4 N (given in the table), where P1 should be the pressure at the point of the flow where velocity is 60m/s. What is the pressure given in the table referred to as? I am confused with static/dynamic and total pressure! Would any kind soul please help? Thanks alot in advance!
