Hii! I'm having an issue with the following equation.

Arun_15_0-1680257653011.png The resulting value should be 3. But Mathcad shows it as 2.731.

It leads to the least resultant value in the further following equations.

Can anyone suggest to me the possibilities of getting the correct result?

We can't debug a picture so you always should attach your worksheet.

You don't show how rho and rho.0 are calculated.

Chances are that their precise values are NOT exactly 0.002 and 0.006 but they are just shown rounded to three decimals.

Let them display with more decimals and see what happens.

Example:

Hi,

display more than 3 decimal places and you will see that the result is correct.

Hii Werner, I understood your solution and that's how the input was. The values of ρ0 and ρ are rounded to three decimals that differ from the actual values.

Thank you!
