I may get confused on this. Increasing diameter lowers the pressure, but, increases volume. In a house we normally use a large pipe as a main and it supplies volume. Then we decrease pipe size to various Faucets and Water Heaters depending on their input size. When done properly you can flush a toilet without the shower burning someone. A sink Faucet will have more pressure from less diameter, but, it will have less volume. So, a sink faucet may fill a gallon jug slower than the Garden Hose Faucet. I hope I explained this correct. Been a while I worked with this stuff.
Yea, what is said above more correct, I give them a Thumbs Up. Velocity what I was trying to think of. Like a spray nozzle on a Garden Hose. The velocity make it seem it more pressure.

The question is incomplete. the question should be
Does making the diameter of a pipe (BIGGER/SMALLER) make the pressure less or greater. ? now i will answer this
1. The pressure has nothing to do with the diameter of pipe.
2. By reducing the pipe diameter the velocity increased. Thus it is presumed that the pressure is increased. for example when we water the plants in garden, put a finger near the pipe in the flow. the jet of water goes far.
3. By increasing the pipe diameter the velocity decreases and thus it is presumed that the pressure is decreased.

If you have a flow within one diameter pipe, and you decrease that flow, the pressure doesn't change but the velocity does increase. The same is true for the reverse, except that the velocity decreases. The pressure is constant throughout a piping system (closed loop).

this paradox has been around for the a while for individuals to evaluate. as scientist all of us comprehend the respond because of the fact we are able to objective the hypothesis with experiments. the respond, from chemistry, air is compressed in quantity by ability of stress. PV=nRT quantity is the reciprocal of stress if mass and temperature is held consistent. greater stress, much less quantity, that's what makes the piston pass. What motives the stress? this is not the burden in column, in fact the column would desire to get replaced by ability of open water in a lake. this is the top of the water column that generates the stress, not the rest. not diameter. to be greater precise this is the reaction of earth gravity on the mass of water, yet that's simplified by ability of only thinking the top.

If you make the diameter smaller, the pressure will increase. And if you enlarge it, pressure will go down. Of course, provided that you keep the other variables the same. Pressure must increase in order to maintain the flow rate.

diameter has nothing 2 do with pressure diameter change affects the velocity
Q= A*V

For a given flow, larger pipe diameters will cause higher pressures (due to decreased flow velocity) than smaller pipe diameters.

Bernoulli's equation states that total HEAD remains constant, not pressure.

it depends on the diameter of the pipe,"smaller",more pressure,larger,"less" pressure.
