Aerodynamics engineers obtain the lift and pressure drag by integratin

1.	Aerodynamics engineers obtain the lift and pressure drag by integrating the ___________ distribution over a surface.(a) Velocity(b) Pressure(c) Temperature(d) ViscosityI had been asked this question in my homework.Query is from Research and Design Tool in section Philosophy of Computational Fluid Dynamics of Computational Fluid Dynamics
Answer» Correct choice is (b) PRESSURE Easiest explanation: LIFT force can be obtained by the difference in pressure between the top and BOTTOM surfaces of a body. Similarly, the pressure drag of a body can be obtained by finding the pressure difference between the front and BACK halves of a body. Both of these quantities DEPEND upon the pressure distribution.
