Exercise E1.7.1 Power loss and efficiency II
A water pump ($\eta_\rm P = 60~\%$) has an electric motor drive ($\eta_\rm M=90~\%$). The pump has to pump $500~{\rm l}$ water per minute up to $12~{\rm m}$ difference in height.
- What must be the rated power of the motor?
- What current does the motor draw from the $230~{\rm V}$ mains? (assumption: the $230~{\rm V}$ is a DC value and also the current is DC)

Reveal.js Test
This is a test suite for the Reveal.js plugin.
These are notes. They are only shown on the wiki page.
- Lists in notes are always NOT incremental
- This is because you would have to press for each list entry the next button without seeing anything
echo 'Hello World'; // code block inside notes

Header level test
Test, if an H3 section following an H1 section is appended horizontally or vertically.
Header level test
Test, if an H4 section opens a new slide. Should not the case for horizontal_slide_level = 2
Alternative Slide Indicator
---- salmon wiki:dokuwiki-128.png 10% repeat bg-slide ---->
This slide has no content, but therefore a fancy background…
It's cool, isn't it?
Zoom
---- orange bg-zoom ---->
This could be a slide without content, not possible in header driven mode…
Horizontal
---->> Horizontal
Horizontal again and stopping special hr driven mode
---->> Horizontal again and stopping special hr driven mode <----
Options (Caching)
If you disable the cache for the page, then you are able to change the options direct in the URL.
In case your theme does not match the environment for the presentation you can fix this very fast without editing the page.
List
For this page/presentation the option build_all_lists
is switched on - the list is therefore shown incremental:
- Unordered list, item one
- Another item
- Ordered sublist
- Another sublist item
- A third item for testing
Fragments
Fragment (inline)
<fragment>text</fragment>
Hit the next arrow…
… to step through …
… a fragmented slide.
Fragment (inline)
Inline Fragments supporting only formatting and substitutions:
DokuWiki supports bold, italic, underlined and monospaced
texts.
Of course you can combine
all these.
You can use subscript and superscript, too.
You can mark something as deleted as well.
Fragment Block
With <fragment-block> you have more or less no limits:
<fragment-block 2>
This comes second
<fragment-block 1>
$number = intval($test); //this comes first :-)
Fragment List
<fragment-list> overwrites the global option build_all_lists:
- List item 1
- List item 2
- List item 3
No Fragment List
<no-fragment-list> overwrites also the global option build_all_lists:
- List item 1
- List item 2
- List item 3
Fragment Styles
<fragment StyleName>
grow
shrink
fade-out
fade-up (also down, left and right!)
current-visible
highlight-current-red (blue, green)
Highlight red blue green
Attention: grow, shrink, fade-up/-down/-left/-right
are only working with <fragment-block>
Background Orange
{{background>orange}}
Background
This slide has black background.
Quotes
This is the original example from the DokuWiki syntax description. For Reveal we suppress the nesting, because the quotes are shown in a different way:
I think we should do it
No we shouldn't
Well, I say we should
Really?
Yes!
Then lets do it!
