Find the Formula for Diameter of 3 Pipes

In summary, the conversation is about a homework problem involving finding the diameter of a pipe using a formula that includes the measures of three pipes and relates to the topic of momentum and forces. The formula is represented by δ[adm]=2%(l1+l2+l3) and the desired result is to find the diameter of the upper pipe. The conversation also includes a suggestion to explain the formula in words for better understanding.

Homework Statement



My vocabulary is pretty bad in specialized English, so I have to post a picture of problem

There are three pipes, the cross-section changes and all measures are illustrative, I need to find an easy formula to find the diameter of d3, so I can create formula in Excel and by changing numbers it calculates the answer.

δ[adm]=2%(l1+l2+l3)


Homework Equations



Formulas are from topic of momentum and forces,
Maybe this helps
δ= M/W ⩽ δ[adm]

The Attempt at a Solution



It should become something like ω/M max * some coefficients, but I haven't found anything form books.

Perhaps if you were to explain in words what this formula is about, someone might recognize what you are trying to do.

It means that the max refraction is 2%. The point is to find diameter of the upper pipe. It depends of the two others.
 

FAQ: Find the Formula for Diameter of 3 Pipes

What is the formula for finding the diameter of a pipe?

The formula for finding the diameter of a pipe is: diameter = 2 x (area / pi)^(1/2), where area is the cross-sectional area of the pipe and pi is the mathematical constant approximately equal to 3.14.

How do I measure the cross-sectional area of a pipe?

The cross-sectional area of a pipe can be measured by using a ruler or tape measure to find the diameter of the pipe, and then using the formula for finding the area of a circle (area = pi x (diameter/2)^2) to calculate the cross-sectional area.

Can the formula for finding the diameter of a pipe be used for different types of pipes?

Yes, the formula can be used for any type of pipe as long as the cross-sectional area can be measured and the value of pi remains constant.

What are some common units of measurement for the diameter of a pipe?

The diameter of a pipe is commonly measured in inches or millimeters, but it can also be measured in centimeters, feet, or meters depending on the size of the pipe.

How accurate is the formula for finding the diameter of a pipe?

The formula is generally accurate, but it may not be precise in every case due to factors such as irregularities in the shape of the pipe or errors in measurement. It is always important to double-check your calculations and take into account any potential sources of error.
