"Engineering mathematics" in Mathcad

I'm not a mathematician, but I think it is wrong to Mathcad Prime apply a hint of the new Combined matrix operator "norm of a vector or matrix"
The right is: "Length of the vector or the determinant of a square matrix."
I see a lot discrepancies or apparent errors in the tooltips Mathcad Prime. I showed them to mathematicians. They say it's not just a mistake - it is so named "engineering understanding" of mathematics. Nine out of ten engineers say that the vector length is the number of elements in it. And not just because Mathcad is a function of length (v), returns not the vector length but a number of elements (components?) in vector, but because for the majority of working with Mathcad think that the vector is not a vector in the mathematical interpretation (not scalar), but simply a table column.
What do you think about this?

Can you explain why you need to convert units using a textbox? Just so we have a better understanding of what you are trying to achieve.

Hey MIke,

I am making the calculation sheet for pressure drope calculation in high pressure piping for power plant.

I am using textbox for adding my inputs which are in different units.

For this i am using list box/combo box.

When i am difining the Temperature in deegre celsius it shows the error THIS VALUE MUST BE SCALAR.

Click the 'Use advanced editor' in the top right corner and then you will be allowed to upload documents.

Hey valery can u guide me how to find dynamic viscosity of steam as function pressure and temperature.

There is no way to transfer units typed in a textbox to the output variable. You will have to use the technique Valery shows, or something similar (I would use a listbox rather than radio buttons, but that's just a personal choice).

Can any one guide me how to find dynamic viscosity of Steam at particular temperature and pressure.

Please (thru Mathcad server - http://twt.mpei.ru/MCS/Worksheets/rbtpp/eng/Diag4.xmcd 😞

http://twt.mpei.ac.ru/ochkov/WSPHB/wspDVPT.gif

or thru DLL (see www.wso.ru)

Hey Valery Thanks lot for your reply.

I am using Mathcad version 14.Can u guide me how can i get WaterSteamPro (General) and how can i install it in my system or mathcad.

Please reply as soon as.

Thanks

Thanks for the interest to WaterSteamPro.

All instructions are here - www.wsp.ru

You must install the program and get the access thru e-mail orlov@twt.mpei.ac.ru

Hey Valery

How can i Referance my Excle sheet to my Equiation and How my Result direct select the value from the given table.

Suppose i want Viscosity as result i have input of pressure and temperature.

I have table in which different value of viscosity calculated according to the different pressure and tempearture.

How can i get viscosity by giving input of pressure and tempearture?

Thanks,

Why "Hey Valery"?

Must be "Hey All"!

You can use WaterSteamPro in Excel too:

See http://www.wsp.ru/en/samples/wcu/excel/wcu_excel.htm

Hey Valery Thanks But I need editable copy because i have to calculate no. of datas.

U can send editable copyif it possible to you to my Email addres.

It is Mayur.Patel4@essar.com or -

Thanks,
