1. The problem statement, all variables and given/known data Find the direction of the force exerted by the fluid to the airfoil. 2. Relevant equations N/A 3. The attempt at a solution I think that's the forces direction (x is horizontal and z is vertical) for 2 cases. In case I am dealing with either the compressor or turbine, will the solutions change? I know that: -If case 1 is designed for the compressor, it will move downward and if case 1 is designed for the turbine, it will move upward. -If case 2 is designed for the compressor, it will move upward and if case 2 is designed for the turbine, it will move downward. I am guessing my directions (forces exerted by the fluid on the airfoil/blade) stay the same. Are my directions right in those 2 cases? Thank you.
