The speed of water flow is the current.
The speed of vessels traveling over water may be measured in 'knots" (meaning nautical miles per hour).
velocity
The technical term for the speed of water is "flow rate," which refers to the volume of water passing through a specific point over a certain period of time. This is commonly measured in cubic meters per second (m³/s) or liters per minute (L/min).
The term for increasing speed is accelerating.
The technical term for the speed of a river is velocity.
With regard to boating, the term Speed of Advance can refer to either the speed of the boat through the water as a function of prop rotation only (no current or drift effects), or the particular speed a boat must maintain in order to cover a specific distance in a specific amount time.
The term for the speed of speech is "rate" and the term for the speed of movement is "velocity."
Not the speed of sound.
Velocity is the term for speed in a specific direction. It is a vector quantity that includes both the speed and direction of an object's motion.
The term for the disturbed water left behind as a boat moves through water is called a "wake." A wake is created as the boat displaces water, resulting in waves that trail behind it. The size and shape of the wake can vary depending on the boat's speed, size, and design.
Speed of light in water = speed of light in vacuum/refractive index of water
"speed" or "the speed"
Terminal velocity is the term for the highest attainable speed an object can reach as it falls through a fluid, such as air or water. At terminal velocity, the force of gravity pulling the object down is equal to the drag force acting against it.
