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
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.
4 gallons if head delivers 2 gallons/minute
It is over 9000 in a ten minute shower
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.
th diameter of this is 7000 litres

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.
A shower head would use between 60 to 75 gallons for a 30 minute shower.
Between a 500-gallon-per-minute pump and a 2,000-gallon-per-minute pump.
Most modern shower heads (U.S.) are restricted to 2.0 gallons a minute or less, so a ten minute shower would use approx. 20 gal.
