AI Thread Summary
Understanding equations in engineering, particularly for volumetric flow rate, requires context and familiarity with the symbols involved. Without specific references or definitions for the variables, providing an intuitive explanation is challenging. Some equations, like F = ma, are universally recognized, but the equation in question lacks sufficient context for interpretation. It may relate to fluid dynamics, possibly resembling the Hagen-Poiseuille equation, but clarity on the symbols and their meanings is essential for accurate understanding. Contextual information is crucial for interpreting engineering equations effectively.

Hi all,

I'm not good at calculus, but want to interpret intuitively various equations in engineering papers.
One of example is below,

This is an equation for volumetric flow rate.

Can anybody explain this equation in a easy way or like literature?James

Without a reference to a paper or book, it is impossible to give you a good explanation of what this equation describes. Throwing out unfamiliar equations without any context is like that, unfortunately.

There are certain equations, like F = ma or E = mc2 which are universal enough that one can make a reasonable interpretation without much additional information, but your sample equation is not one of these.

Try to make sense out of the dimensions. If that's an equation for volumetric flow rate the dimensions must be [L]^3/[t]
 
It might help if you said what each of the symbols represents: V, P, z, ω, μ, α
and what the formula is supposed to calculate an in what context.
 
It bears a passing resemblance to the Hagen-Poiseuille equation, so I'd hazard a guess that this has something to do with fluid flowing in a pipe (or several pipes, given the summation), but it isn't really a match so I really don't know without any more context.

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
