Head loss will decrease
Head pressure is created by a column (depth) of water in a container. Pipe is considered a container. Diameter is not a factor. The higher the column of water, the more psi it creates. Multiply column height of water by .434 to get psi of water.
300mm is a very low head, you can't expect much flow through that pipe, but you can work it out from the mechanical energy balance equation.
You can place functions in the head section. They will be styled the same way head is styled.
It gets wet.
The sprinkler head design. High velocity heads have longer nozzles with a venturi tube (a type of curved nozzle) which increases the velocity of the water spray. Medium velocity heads are shorter and do not use a venturi.
the deeper you go , the more water is on your head

Head is the Circumference which is Pi*Diameter where pi=22/7
It is part of the migraine. Recently read of a possible fix: put your feet in very warm water; put ice on your head. This increases circulation to your head and may make the migraine go away.
The size of a pin head is roughly two mm in diameter. The size of a sewing needle head is roughly five mm in diameter.
You have a blown head gasket.
There isn't one. Pressure in a piping system will be determined by the pump, or head of water if it is a gravity feed system.
No. Pascal's Principle states that a pressure applied to a fluid system at rest is felt throughout the entire system. This means that, regardless of pipe diameter, city pressure is felt everywhere. Decreasing pipe diameter will only reduce the flow rate of the water, due to more head loss when the water moves.
Water column head is expressed either as the height of the column ... 6 meters here ... or else as the pressure at the bottom ... 58.842 kPa here. 'Kg' can't be a unit of water column head, and the diameter of the column is irrelevant.
