Math & Science ⇒ alignment equation/label

[stewbi]

Hi everyone, I've a little problem with the alignment of the label of the equation.
My goal is to obtain a centered equation with its label on the right side

• ..................................dh = cp dT +vdp.............................(1.2)

I'm using :

Code: Select all

\documentclass[12pt,a4paper,twoside,openright,reqno]{book}

If by this code:

Code: Select all

\begin{equation}
  \begin{center}
    $dh=c_p dt+vdp$ \label{}
  \end{center}
\end{equation}

I delete the \begin{center} TeXnicCenter write the equation on left side and the label on the right but with it I get the equation centered but the label on left side of new line, like this:
.................................dh = cpdT +vdp....................................
(1.2)
idea?
thanks for your help

The dollar signs, and i think the center-environment as well, are wrong in an equation-environment.

Code: Select all

\documentclass[12pt,a4paper,twoside,openright,%reqno 
]{book}
%\usepackage{showframe} %shows a frame around the typearea
\begin{document}
    \begin{equation}
        dh=c_p dt+vdp \label{}
    \end{equation}
\end{document}

$<math>$ changes to LaTeX-Inline-Math-Mode, whereas the equation-environment changes to display-mathmode. Centering the equation is the default, and changes should be made uniformly using a documentwide option to documentclass.

May I ask, where this code is coming from?
