Man I am tired. I guess that would give me what I need. Dividing by gravity is going to give me a mass value. So this would be right. Thank you. How would I get the propeller efficiency coefficient? Thanks
Sorry about that. Yes the fan is mounted vertically, pulling air from below creating a thrust (Force) reacting at the contact points. The reason, I thought, to divide this thrust by gravity would be to get my value in weight, rather than force.
Yes, I just did not know the required variables needed. I am a young structural engineer, not aerodynamic. I have calculated thrust being F=(mass flow)(air velocity). My calculations provided a value with the units lb-ft/s^2, so I'm assuming I divide this by gravity to get lbm. The answer is...
I am a young engineer, and trying to understand the design criteria for Seismic Loading of ASCE 7-10 (Simplified Alternative Design Criteria). For a cooling tower (50ft), how many stories would this be considered. Would this exceed the 3 stories above grade plane? Since this is not an occupied...
