1 liter is ~ quart, so 2 L ~ half gallon, , 1L is 1000 cc (cm^3) so ~2000 cc/min flow rate 1 m is 3 feet 3 inch, so 8 m is ~ 25 ft (26) so 800 cm long, and half inch diam is 1.2cm, and the cross section is pi xradius^2; so 3.14 x (0.6)^2 ~ 1.26 cm^2, so the volume of pipe to fill is 800 cm x 1.26 cm2 ~1000 cc. so 1000cc/2000 cc/min gives about 0.5 min, 30 sec
Easy to figure out 2.2 * 8 = 17.6
A standard showerhead typically uses about 2.5 gallons of water per minute. Therefore, a 5-minute shower would use approximately 12.5 gallons. Since there are 16 cups in a gallon, this equates to about 200 cups of water for a 5-minute shower.
over 5 gallons of water but if you take a 10-15 minute shower you can save a half a gallon of water by 6min. to 5min.
The amount of water saved by taking a 5-minute shower instead of a 10-minute shower depends on the flow rate of the showerhead. For example, if the showerhead has a flow rate of 2.5 gallons per minute, a 10-minute shower would use 25 gallons, while a 5-minute shower would use 12.5 gallons. Therefore, you would save approximately 12.5 gallons of water by reducing your shower time by 5 minutes.
Modern shower heads are mandated to allow 2.5 gallons per minute through them. If it is an older shower head that could be up to 8 or 9 gpm. An easy test is get a five gallon bucket and let the shower run into it for a timed minute. You can measure up the side and see if fills about 1/2 of the bucket or not.

A ten minute shower can use less water than a full bath. With a new 2.5 gallon-per-minute (low-flow) shower head, a 10-minute shower will use about 25 gallons of water, saving you five gallons of water over a typical bath. A new showerhead also will save energy — up to $145 each year on electricity — beating out both the bath and an old-fashioned showerhead. To avoid moisture problems, control humidity in your bathroom by running your ventilating fan during and 15 minutes after showers and baths.
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.
