Derivation of formula for capillary action

AI Thread Summary
The formula for the height of liquid rise in a capillary tube is derived from the balance of adhesive forces, surface tension, and the weight of the liquid column. The adhesive force pulls the liquid up, while the surface tension acts along the perimeter of the tube, and the weight of the liquid opposes this rise. To find the height, one must understand the relationship between these forces, particularly the contact angle θ, which affects the effective surface tension. Resources such as HyperPhysics and Wikipedia provide valuable insights into surface tension and capillary action, aiding in the derivation process. Understanding these concepts is crucial for successfully deriving the formula.

the height upto which liquid rises in capillary tube is 2S cosθ / ρgR
I need a derivation for this - please
I know that a combination of adhesive force , surface tension and weight creates the contact angle θ but how to proceed after that?
To calculate height h i need to know the force by which tube is pulling the liquid(adhesive force) but how can i know that?

Its really important for me to know the derivation so please help me

hope this helps.. too lazy to type the whole thing.. also read articles on wikipedia baout surface tension and capillary action.. you should be able to figure out..
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
