a) Pressure within a system that is greater than the environment that surrounds that system.
b) The force applied to a unit area of surface.
c) Often called back siphonage, is something that creates a vacuum in the Water System and allows water to be 「sucked」 back into the system.
d) Pressure within a system that has equilized with the environment that surrounds that system.
