Approx. 15 to 20 litres are used in a single shower
It would depend on the shower speed setting

Can't say because this depends on the flow coming out of the shower head. If the flow is 1ltr per minute then in 10 minutes you will use 10 litres The average shower in the US flows at a rate of 7.9 liters per minute, or 2.1 gallons per minute. A ten minute shower would consume 79 liters or 21 gallons of water.
This is impossible to say as all showers are different.
Yes, yes they do reduce water consumption. Also, much like a filter for your tap water, it will help to offer cleaner water in the shower for both your water and hair.
If you mean how much does it hold when entirely full, it can't be answered without knowing the size. If you are asking how much is used, again without know how long you let the water run or how many minutes, this can't be answered either.
We can't provide graphs on WikiAnswers. However, here is an answer to a similar question: It depends on your shower head and whether it has a flow restrictor in it and how long you shower. If your home was built before 1992, chances are your showerheads put out about five gallons of water per minute (gpm). Multiply this by the number of minutes you're in the shower, and the water adds up fast! An average bath requires 30-50 gallons of water. The average shower of four minutes with an old shower head uses 20 gallons of water. With a low-flow shower head, only 10 gallons of water is used. To test the amount of water used in a shower vs. a bath is to put the plug in the bath next time you take a shower (but not a stand-alone shower as you might spill over the lower shower wall). After you've showered, see how much the tub filled up. If there is less water than you would usually have in a bath, then you will probably save money by taking a shower instead of a bath.

It depends on the length of the shower, and the flow of water. Shower heads can usually allow anywhere between 2.5 and 5 gallons of water a minute. Most baths require 30-50 gallons of water. To save energy the length of the shower x, multiplied by the water flow y, must equal less than the amount of water used in the bath. X*Y (Minutes/Gallons) < Gallons in Tub
It is over 9000 in a ten minute shower
