Liquid pressure gradient in zero gravity

AI Thread Summary
In a zero-gravity environment, a floating liquid sphere experiences a uniform pressure internally if gravitational effects are neglected. The pressure inside the sphere is higher than the external pressure by an amount determined by the surface tension, specifically 2σ/R, where σ is the surface tension and R is the radius of the sphere. Discussions highlight the significance of surface tension in creating a pressure gradient. There is a lack of specific data on measurements of these pressure gradients in zero gravity. Understanding these principles is crucial for applications in fluid dynamics in space.

Is there any data about such measurements?
I think, there has to be a pressure gradient in a floating liquid sphere due to surface tension.

Hi Malverin. Welcome to Physics Forums.

If you are neglecting the fluid's gravitation on itself, then the pressure will be uniform within the sphere. It will exceed the pressure outside by 2σ/R.

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...
