[Tex/LaTex] “Water–pattern”: a mechanical system

patterntikz-pgf

I was reading an old book and I found a picture which I reproduced with TikZ. Here is the original:

And here is my attempt and a MWE:

\documentclass[border=5pt,tikz]{standalone}
\usetikzlibrary{arrows,patterns}
\begin{document}
    \begin{tikzpicture}[thick,>=latex,every node/.style={font=\sf\em}]
        \draw[double distance=2mm] (3,1) --+ (.4,0);
        \draw[double distance=2mm] (3.7,1) --+ (.4,0);
%           \draw[xshift=5.1cm,yshift=-.385cm,double distance=2mm] (0,0) -- (2,0) -- (3,5);
                \draw[rounded corners] (0,0) rectangle (3,2);
                    \draw (.2,0) --+ (-.2,-.5);
                    \draw (2.8,0) --+ (.2,-.5);

                \draw[xshift=3.4cm,yshift=.75cm] (0,0) rectangle (.1,.5);
                \draw[xshift=3.6cm,yshift=.75cm] (0,0) rectangle (.1,.5);

                    \draw[xshift=4.1cm,yshift=-.5cm] (0,0) rectangle (1,3);
                    \draw[xshift=2.5cm,yshift=1cm,densely dotted] (0,0) -- (2,0);

        \draw[xshift=5.1cm,yshift=-.5cm] (0,0) -- (2,0) -- (3,5) --+ (2,0);
        \draw[xscale=.97,yscale=.957,xshift=5.1cm,yshift=-.3cm] (.15,0) -- (2,0) -- (3,5) --+ (0,1);

            \draw[xscale=.97,yscale=.957,xshift=5.1cm,yshift=-.3cm] (3,5) --+ (-1,0);
            \draw[xscale=.97,yscale=.957,xshift=7cm,yshift=-.3cm] (3,5) --+ (0,1);

        \draw[very thick,yshift=-.5cm] (0,0) -- (8,0);
        \draw[thin,yshift=-.5cm] (8,0) -- (9.9,0);

            \node (a) at (1.5,4) {Dieselmotor};
            \draw[->] (a) --+ (0,-1.5);

                \node (b) at (4.6,4) {Kreiselpumpe};
                \draw[->] (b) --+ (0,-1.5);

            \draw[<->] (9.9,-.5) -- (9.9,4.5) node[midway,fill=white] {$h$};

            \fill[pattern=north west lines,xshift=5.1cm,yshift=-.5cm] (0,0) -- (2,0) -- (3,5) -- (4.6,5) -- (4.6,5.6) -- (2.76,5.6) -- (2.75,5) -- (1.8,.2) -- (0,.2) -- cycle;
    \end{tikzpicture}
\end{document}

How can get I the pattern which is used to simulate the fluid in the tank and the pipe (see original drawing)?

P.S.: Of course I could just use the pattern=north west lines from the TikZ library patterns, but I want another style. My MWE is pretty messy (as always), so don't wonder that some things could be done better. 😉

[Tex/LaTex] pgflayer: background and foreground and tikz: pattern for water

I have re-drawn the cylinder and filled it with white so that whatever is drawn on background layer, is not visible. Further, by manipulating the dash pattern and using \foreach loop with some xshift, the desired effect can be achieved.

[Tex/LaTex] A Mechanical System in Tikz

The white spaces on the north and east side of the corner box are due to the nodes having non-zero inner sep and outer sep by default. The other changes which can be made are to position the nodes relative to other nodes and by making use of node anchors.

Just by adding inner sep=0pt,outer sep=0pt to \tikzstyle{ground}{...} solves your problem with the corner square.

However the vertical piece of wall is still positioned awkwardly, we can replace \node (wall) [ground, rotate=-90, minimum width=3cm,yshift=-3cm] {}; with \node (wall) [ground, rotate=-90, minimum width=3cm,anchor=south east] at (fill.north west) {}; to specify that the south east corner of the wall after it has been rotated by the -90 degrees (so in the image the south west corner) should be place at the north west corner of the corner block.

\draw [-latex,ultra thick] (M.east) ++ (0cm,0cm) -- +(1cm,0cm);
\end{tikzpicture}
\end{document}

In response to the OP's updated code I made a few changes, largely defining nodes along paths so they are placed more automatically. For example

\draw [-latex,ultra thick] (M.north east) ++ (0cm, 0.5cm) -- +(1cm,0cm);
\node (y1) at (M.north east) [xshift = 1.2cm, yshift = 0.5cm] {$y_1$};

Can be replaced by

\draw [-latex,ultra thick] (M.north east) ++(0cm, 0.5cm) -- +(1cm,0cm) node [right] (y1) {$y_1$};

which places the y1 node at the end of the arrow which has just been drawn, which to my eye already puts the $y_1$ label in a natural position, to me this makes more sense than defining the position of the node with respect to the start point of the arrow. One can still use xshift and yshift for fine positioning of course but those shifts now need only be much smaller adjustments (as I have done below to position the b node).
