I want to draw the propeller, which is mixing the water in the pool.In attached file you can see my drawing. How can I develop this drawing?

\documentclass[tikz,border=5]{standalone}
\begin{document}
\begin{tikzpicture}
\draw[line width = 10pt] (-0.75,0.5) -- (-0.75,-2.75) --
    (3.0, -2.75) -- (3.0,0.5);
\draw[join=round, line width = 5pt, color = gray!25] (-0.75,0.42) --
    (-0.75,-2.75) -- (3.0, -2.75) -- (3.0,0.42);
\draw[join=round, line width = 10pt] (-1.5,-2.75) -- (-0.85,-2.75) ;
\draw[join=round, line width = 5pt, color = gray!25] (-1.5,-2.75) -- (-0.7,-2.75) ;
\draw[join=round, line width = 10pt] (3.10,-2.75) -- (3.75,-2.75) ;
\draw[join=round, line width = 5pt, color = gray!25] (3.00,-2.75) -- (3.75,-2.75) ;
\fill[gray!40!white] (-0.57,-2.57) rectangle (2.83,0.0);
\draw[rounded corners=2pt,fill=black, ultra thick] (0.8,-0.5) -- (2,-0.4) -- (2,-0.6) -- cycle;
\draw[rounded corners=2pt,fill=black, ultra thick] (1.2,-0.5) -- (0,-0.4) -- (0,-0.6) -- cycle;
\draw[join = round, ultra thick] (1,-0.50) -- (1,2.5);
\draw[-latex,thin](-1.5,-1.50)node[above,scale=1.0]{\scriptsize{$25^{\circ}C$}} to[out=-80,in=150] (-1.5,-2.70);
\draw[-latex,thin](2.0,1.0)node[above,scale=1.0]{\scriptsize{$90^{\circ}C$}} to[out=-80,in=100] (2.0,0.00);
\draw[-stealth,thin](0.75,1.25) to[out=-80,in=-120] (1.25,1.25);
\end{tikzpicture}   
\end{document}

    Some people take exception to questions of the form "Please draw this for me". You will get more help if you post some code showing what you have tried and give a minimal working example. – Andrew Mar 21 '16 at 12:13

Using 'controls' and replacing only the two lines (instead of '\draw[rounded corners=2pt,fill=black, ultra thick]...') related to the propeller drawing :

\draw[fill=black] (1,-0.5) .. controls (1.4,-0.4) and (1.8,-0.3) .. (2,-0.5) .. controls (1.8,-0.7) and (1.4,-0.6) .. (1,-0.5);
\draw[fill=black] (1,-0.5) .. controls (1.4,-0.4) and (1.8,-0.3) .. (2,-0.5) .. controls (1.8,-0.7) and (1.4,-0.6) .. (1,-0.5);

will give you a nicer shape ! By the way, propeller is probably not the word you want to use, may I suggest stirring blades or stirring impeller instead.
