Unit Error

[Arun_15]

Hii,

     I am facing another error regarding the unit.

It shows that the units are not compatible. What it means and how to solve this?

Hi,

you add "problematic" expression to constant 11. Therefore the expression must be unitless ... please take a paper and pencil and check it.

Example:

Thank you, Mr.Martin!

The equation contains no unit for the numbers. Is there any other way to get the result?

Your expression can only work if f.ck is unitless and rho.0 and rho have the same unit. The simple reason is that you are adding the unitless 11 to parts involving those variables and subtracting the unitless 1 from the division of rho.0 and rho .

Next time, please attach the worksheet.

Success!

Thank you, Luc!

             Now It's clear. Will try.

Cheers!

Hi Arun,

It is another empirical equation using square root of f.ck do this:

Thank you, Terry!

      I'd tried it before, but it had not worked, and now it's working. Previously I couldn't assign the values correctly, I think so!

Thank you again, Terry! It was very helpful.

Cheers🥂

Hi Arun

Sometimes when typing the MPa under the f.ck Prime tags it with the variable label automatically.

In this case you need to assign it as a unit label. highlight it and set label as unit

Then you get the MPa as units

Thank you, Terry!

             I'd faced this before and solved it on my own.

Thanks for your concern.

Cheers
