The answer to that question is " Piezometric plane". Though in reality the correct definition of Piezometric plane is actually "The equivalent elevation head (EH) of water at the point force is measured", what they are talking about when they say "equivalent" is that imaginary line.

What does the cross symbol mean on a contour map?
The cross symbol on a contour map typically indicates the location of a benchmark, which is a point of known elevation used as a reference for determining the elevation of other points on the map. It serves as a fixed point for surveyors and map users to use as a reference for measuring heights and depths.
How do imaginary lines on the globe help ships?
Imaginary lines on the globe, such as the equator and meridians of longitude, help ships navigate by providing reference points for determining direction and location. These lines help sailors plot courses, calculate distances, and establish time zones, contributing to safe and efficient navigation at sea.
What is arbitrary meridian?
An arbitrary meridian is an imaginary line running from the North Pole to the South Pole that is chosen as the starting point for measuring longitude on a map or globe. It helps establish a reference point for determining the east-west position of a location on Earth.
Elevation at sea level is what?
The elevation at sea level is defined as 0 feet or 0 meters. This serves as a reference point for measuring elevations above or below sea level on land.
What is geographic meridian?
A geographic meridian is an imaginary line that connects the North Pole with the South Pole. It is used as a reference point for determining longitude on Earth, with the Prime Meridian (located in Greenwich, England) being the most commonly used meridian.
What is the most common reference point for determining position and motion?
Earth's surface is a common reference point for determining position and motion.
What does the cross symbol mean on a contour map?
The cross symbol on a contour map typically indicates the location of a benchmark, which is a point of known elevation used as a reference for determining the elevation of other points on the map. It serves as a fixed point for surveyors and map users to use as a reference for measuring heights and depths.
What does BM stand for in surveying?
BM in surveying stands for "Bench Mark." It is a point of known elevation used as a reference for conducting leveling surveys. Bench Marks are typically physical markers installed in the ground or on a structure that serve as a consistent point of reference for determining elevations.
How much feet is in sea level in Hawaii?
Sea level is 0 feet, period - that's the reference used for determining land elevation. Sea level is the same in Hawaii as it is in Siberia or anywhere else.
What is the formula for determining the reference front of pigment?
The formula for determining the reference front of pigment in thin layer chromatography is: Reference front = distance traveled by pigment / distance traveled by solvent.
For determining motion the surface of earth is a common?
reference point
How do imaginary lines on the globe help ships?

These lines help sailors plot courses, calculate distances, and establish time zones, contributing to safe and efficient navigation at sea.
What is the height of an object above a reference point?
The height of an object above a reference point is the vertical distance between the object and the reference point. It is commonly measured in units such as meters or feet. The height is determined by subtracting the elevation of the reference point from the elevation of the object.
What is height above sea leval?
Height above sea level is a measurement of how high an object or location is in relation to the average sea level. It provides a reference point for determining elevation and is commonly used in geography, navigation, and surveying.
What is arbitrary meridian?
An arbitrary meridian is an imaginary line running from the North Pole to the South Pole that is chosen as the starting point for measuring longitude on a map or globe. It helps establish a reference point for determining the east-west position of a location on Earth.
What is the difference between sea level and elevation?
Sea level ~ average (mean) height of the sea, with a reference to a suitable reference point. Elevation ~ height of a geographic location above mean sea level.
What divided the Earth into eastern and western hemisphers?
The Prime Meridian, located at 0 degrees longitude, is what separates the Earth into eastern and western hemispheres. This imaginary line runs from the North Pole to the South Pole and serves as the reference point for determining east and west.
