Math & Science ⇒ align text

[zainah]

Dear all,
I have an equation below. How to align the text for the symbol description? When I just use \qquad to give the space between the symbol and the definition, its become not align when some of the symbol is not in the same size.

Code: Select all

\begin{equation}
d = N_b \rho c {R_p}^{4}  \frac{C_d}{8} + a \lambda \frac{\theta_{io}}{6} - \frac{\theta_{itw}}{8} - \frac{\lambda}{4}  
\label{eqapp2}
\end{equation}
where\\
$N_b$ \qquad \qquad no of blade per thruster $[-]$ \\
$c$ \qquad \qquad average chord of the blade  $[m]$ \\
$R_p$ \qquad \qquad thruster radius $[m]$\\
$a=2\pi$ \qquad \qquad lift slope  $[rad \ s^{-1}]$\\

Here's what I do mostly:

Code: Select all

...
	where\\
	\begin{tabular}{ll}
		$N_b$ & no of blade per thruster $[-]$ \\
		$c$ & average chord of the blade  $[m]$ \\
		$R_p$ & thruster radius $[m]$\\
		$a=2\pi$ & lift slope  $[rad \ s^{-1}]$\\
	\end{tabular}

As a side note; you might want to use the siunitx package for the units. That is, you might want to try [\si{m}] instead of $[m]$.

Some code snippets from Section 65.2 of the »Math mode« document could be interesting for you.
