creating tanks with tikz

Question

I am trying to create this diagram,

as I am not familiar with tikzpicture, but after going through tutorials, i come up with this:

and the code is:

\usepackage{tikz}
\usepackage{pgf}
\usepackage{pgfplots}
\usetikzlibrary{positioning,shapes,calc, decorations.pathreplacing, arrows, decorations.pathmorphing, backgrounds, fit, shapes.symbols, decorations.text,automata}


\begin{document}
\begin{tikzpicture} %[>=latex,shorten >=2pt,shorten <=2pt,shape
aspect=1] %\node (A) [cylinder, shape border rotate=90, draw,minimum
%height=4cm,minimum width=2cm] %{A};

%\draw (0,0) ellipse (1.25 and 0.5););   \fill [white,opacity=0.5]
(-1.25,0) -- (-1.25,-3.5) arc (180:360:1.25 and 0.5) -- (1.25,0) arc
(0:180:1.25 and -0.5); \draw (-1.25,0) -- (-1.25,-3.5); \draw
(-1.25,-3.5) arc (180:360:1.25 and 0.5); %\draw [dashed] (-1.25,-3.5)
arc (180:360:1.25 and -0.5); \draw (1.25,-3.5) -- (1.25,0);

\draw (-0.3,-4) -- (-0.3,-4.5); \draw (0.3,-4) -- (0.3,-4.5); 

\draw[dashed] (-1.2,-1.5) -- (1.2,-1.5) node [midway,
above,fill=white] {$x_1$}; \draw[dashed] (-1.2,-3.3) -- (1.2,-3.3)
node [midway, above,fill=white] {$r_1$};


\qquad


%[>=latex,shorten >=2pt,shorten <=2pt,shape aspect=1] %\node (A)
[cylinder, shape border rotate=90, draw,minimum %height=4cm,minimum
width=2cm] %{A};

%\draw (0,0) ellipse (1.25 and 0.5); \draw (3.25,0) -- (3.25,-3.5);
\draw (3.25,-3.5) arc (180:360:1.25 and 0.5); %\draw [dashed]
(-1.25,-3.5) arc (180:360:1.25 and -0.5); \draw (5.75,-3.5) --
(5.75,0);   \fill [white,opacity=0.5] (3.25,0) -- (3.25,-3.5) arc
(180:360:1.25 and 0.5) -- (1.25,0) arc (0:180:1.25 and -0.5);

\draw (4.2,-4) -- (4.2,-4.5); \draw (4.8,-4) -- (4.8,-4.5); 


\draw[dashed] (2.9,-1.5) -- (5.7,-1.5) node [midway, above,fill=white]
{$x_2$}; \draw[dashed] (2.9,-3.3) -- (5.7,-3.3) node [midway,
above,fill=white] {$r_2$};


\end{tikzpicture}
\end{document}

I am still alot far, but it would be great, if someone can help me creating this diagram. Thank you.

Welcome to TeX.SX! Can you please expand the code snippets that you have posted to a full minimal working example. It is much easier to help you you if we can start with some compilable code that illustrates your problem. A MWE should compile and be as small as possible to demonstrate your problem. — , Dec 02 '16 at 11:01
Hi @Andrew, Thank you for your time. I have edited it. Is it enough or still some detail is missing? Please let me know. Thank you. — Waqar Ahmed, Dec 02 '16 at 11:36

is there a reason you're not using circle (as for tank's top) for the [densely dashed] part? — ebosi, Dec 02 '16 at 12:21
@ferahfeza Thank you very much for this..:) It is exactly what i was looking for. — Waqar Ahmed, Dec 02 '16 at 17:06
@ferahfeza..one question, can you tell me how to position this picture in centre? I tried "\begin{center}" but it is still somehow on right side. Thank you — Waqar Ahmed, Dec 02 '16 at 17:19
@WaqarAhmed, yourwelcom. For centering, look at: http://tex.stackexchange.com/a/62494/31034 — , Dec 02 '16 at 17:29
