Depending on how many bars of pressure you are talking about and where you live in the world. But generally, copper or galvanised are good options and be sure to use copper compression fittings on the outside and solder joints on the inside if using copper piping.
Operating systems and application software.
Neither Pressure re mains the same the VOLUME changes along with the VELOCITY
In an unvented system, hot water can be at a higher pressure than the cold mains due to the presence of a pressure-reducing valve on the cold water supply. This valve controls the pressure of the cold water coming into the system, allowing the pressure of the hot water, which is heated and stored at a higher temperature, to be higher. Additionally, the expansion vessel in the system helps regulate pressure fluctuations by absorbing excess pressure from heating water.
30 litres per minute
In the combo boiler for the central heating? You need a small piece of hose (or it might have a permanent connection) to fix to the mains from the boiler. Then turn the taps near the boiler for the mains and the boiler. You want the pressure to be about 1.3 bar
It depends on the rectifier. For a half-wave, it's the same as the AC mains: i.e. 60 Hz mains gives 60 Hz ripple. For a full-wave or a bridge, it's twice the AC mains: 60 Hz mains gives 120 Hz ripple. Three-phase systems are more complicated, so you would need to check in an electrical engineering book.

The velocity does not depend on ther shower head, however it does depend on the cold mains pressure, a higher pressure will result in a higher velocity, and visa versa.
Call your city hall or Water Works for the information of what PSI it is set at.
Turn up the mains pressure or replace your water lines if you have galvanised piping, the internal diameter might have been reduced due to rust.
