Air pressure caused by wind on human being

AI Thread Summary
The discussion focuses on calculating the air pressure exerted by wind on a human body at various speeds. A formula is provided: P = 0.00256 x V^2 x C, where P is pressure in psi, V is wind velocity in mph, and C is a shape coefficient. The complexity of the human body's shape makes determining an accurate coefficient challenging. One participant suggests starting the calculations without the shape coefficient, noting that maximum pressure occurs at the stagnation point on the body. The conversation emphasizes the need for further exploration of the shape coefficient for precise calculations.

Hi Folks-
Is there a way to determine the air pressure caused by wind at a given mph on a human being? Thanks!

Yes. The general formula for your units is:

P = 0.00256 x V^2 x C

where,

P is the pressure in psi
V is the wind velocity in mph
C is a shape coefficient (don't know what it would be for a human body since it is such a complex shape)

Hope this helps.

Thanks for the quick response! I'll do some more digging on the shape part and see what I can come up with. Thanks again!
 
I'd start without the shape coefficient - there is a point in the middle of your body where the air stagnates, producing the maximum pressure possible via Bernoulli's equation.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
