When you say 1/2" are you talking about 5/8 OD or nominal size and which type of copper? K /L/ M as there is friction looses to consider
I am referring to 1/2" nominal type L copper pipe, and the friction loss is negligent because the section of 1/2 inch tubing is only 2" nipples on either side of a electric shut off valve. The actual set-up is 1" PVC supply at 65psi, reduction fitting to 3/4" into a pressure redusing valve, 3/4" out of the valve through another reduction fitting to 1/2" into and through the shut-off valve, then into the furnace. Distance from the first 1' to 3/4" reducer to the furnace is only a distance of about 14". Hope this helps.
26 inch......means 650 mm
You do not: it is alll done in pixel, points, etc. What one browser displays as half an inch another may display very differently.
In the USA, 15mm is half-inch, and 22mm is three-quarters inch. Lengths of pipe nipples in these sizes range from one and a quarter/one and a half, to six inches, in half-inch increments.
Depending what you are wanting to supply. Basin, shower, toilet, bidet, kitchen can be fed with a half inch line Main line and bath can be fed with a three quarter inch line
i believe the pressure does not change but the volume of water you will be able to use will be less

It would be wonderful if you also gave the pressure and told about friction losses
The maximum flow rate through a 1.5 inch pipe is typically around 9 gallons per minute.
Given enough time the entire ocean could be pumped through a half-inch pipe.
By the use of Flagg Flow T.P Fitting adapters and Cx M or C x F adapters attached to the T.P fitting T.P = threadless pipe
Mamimum range is about 900 yards. Maximum EFFECTIVE range is about 50 yards.
Yes, easily.
That's 3/4" pipe, not 3.4" prehaps it would deliver more pressure through the 1/2 inch pipe than 3/4 inch. 3/4" pipe will be less restrictive over the course of the run. Otherwise, no. 1/2" Copper Pipe will do fine, since it has a smoother bore, less restrictive, no lime and rust build-up. The only reason for you to use 3/4" pipe is if you want more volume. The pressure remains the same.
half inch
Two quarters of an inch are in a half inch.
Not many. Maybe one at best. Half inch copper line is too small for most needs. 3/4 only costs a little more. You will go completely mad waiting for a bathtub to fill with half inch lines. Every flush of a toilet will make the shower die out.
half an inch!
