For a fluid flowing in a pipe, the pressure loss will be greater for a liquid flow due to more frictional losses on the pipe walls.
w,the pressure in the straw is reduced.but the atmospeheric pressure on the surface of the liquid stays the same.
Pressure decreases.
Sucking on the straw reduces the air pressure inside it. This allows 'natural' air pressure to push down on the liquid in the container, causing it to rise up the straw..
Flow of Liquid
the resistance of a liquid to flow
Static pressure certainly does affect flow rate. Static pressure can slow or speed up flow rate based on the liquid.
the pressure of the liquid that flow through it
You speed up the pump, which increases its pressure on the solid or liquid. Narrowing the pipe does not increase the pressure or flow rate, it only increases the speed at which the liquid or gas passes by a given point.
Maintaining blood pressure.
At constant pressure and constant fluid density, larger pipe results in larger flow rate.
Want to give an idea what pressure ?How about saying is it vapor (steam) or liquid
The basic principle of the syphon system is that the difference of pressure at both the ends of the tube would drive the liquid from the level of higher pressure to that of lower pressure. If, suppose, the level of liquid becomes the same in both the container then flow of liquid would stop. So, if you want to send back the liquid, then you have raise the container above the first one, then liquid would start flow from the second to the first.
you have a severe pressure drop and a loss of velocity
Were liquid is more, you have more pressure. Liquids, and gasses flow from higher pressure areas to lower pressure areas, like people in a bus. If it's crowded is a place, they go were it's less crowded.

Pressure and temperature are the two factors that affect flow and viscosity. Viscosity refers to the resistance of a liquid to the shear forces.
