No, it is not static
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
Residential static water pressure can be measured using a water pressure gauge attached to an outdoor spigot. Simply screw the gauge onto the spigot, turn off all water sources inside the house, and then open the spigot to get a reading of the static water pressure.
The energy behind a fire hydrant that is not flowing water is known as "static pressure". This is the water pressure that is normally available from the water main when the hydrant is closed.
The static pressure you mentioned as 1.5 is basically in 1.5 inch water guage . (i.e measured on a water guage at which the height of the water column is 1.5 inch) So if u want to compare ur static pressure to that of a balloon, you will need to find the static pressure of the balloon to compare both the values.
Dynamic pressure is the pressure exerted by a fluid in motion, caused by its velocity, while static pressure is the pressure exerted by a fluid at rest. Dynamic pressure increases with the square of the velocity, whereas static pressure remains constant regardless of velocity.
When the pump is not running, the water pressure at the output pipe of the pump will be equal to the static pressure of the water source acting on the pipe. This static pressure varies depending on the elevation and depth of the water source.
Static Pressure 20 mm WC means the pressure which can sustain 20 mm high water column.
Force created from the flow of water
The static head the distance to the point of application or the height the pump has to overcome for liquids. For air likewise is almost the same except that it is ducted, refer to Moody chart.The pressure exerted by a still liquid or gas, especially water or air.
Static or pressurized tank?
Pressure (Static) is 0.433*(H). H in feet. answer in pounds/sq inch
Static head of water refers to the vertical distance between the water surface and the point of measurement. It represents the potential energy stored in the water due to its height and is a key factor in calculating pressure and flow in fluid systems.
