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
The maximum flow of water through a 3-inch diameter pipe depends on various factors, including the pressure, the length of the pipe, and the fluid's viscosity. Generally, using the Hazen-Williams equation or other hydraulic calculations, a 3-inch pipe can typically carry around 600 to 1,200 gallons per minute (GPM) under optimal conditions. To determine the precise maximum flow for a specific situation, one would need to consider the exact parameters of the pipe system.

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.
The flow of water through a half-inch copper pipe at 35 psi can be estimated using the Hazen-Williams equation or similar hydraulic formulas. Generally, a half-inch pipe can deliver approximately 5 to 10 gallons per minute (GPM) at that pressure, depending on factors like pipe length, fittings, and flow conditions. For a more precise calculation, additional parameters such as the specific setup and any friction losses would need to be considered.
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.
