Traditionallya ships speedwas measured using a ship's log which was a trailing rope with evenly spaced knots. (hence the term "Knots" meaning nautical miles per hour) Todaya vessels speed is often determined by the rpm's of the propeller (or screw as it is officially called by marine engineers), or by a tube which measures the flow of water passing the hull. In the USA on small motorboats this is often called a speedometer, just as it would be on a motor car. In the rest of the English speaking world it is still called a log, although this should not be confused with the Ship's Log which is written daily account of the vessels movements and actions.

What instrument measures velocity?
In a car, a speedometer. At a weather station, an anemometer measures wind speed.
What is the name of the equipment that measures speed?
This instrument is generally known as a Speedometer.
How many mph can a tug boat go?
Boats/ships don't measure speed in mph.
Is radiation the instrument used to measure wind speed?
No, a barometer measures air pressure. Though wind is caused by variances in air pressure the direct measurement of wind is done by an anemometeryes
What is the name of the wind instrument that measures wind?
An anemometer measures wind speed A wind vane shows the wind direction
Which is an instrument commonly used to measure wind speed?
An anemometer measures wind velocity.
What instrument measures prevailing wind?
An anemometer measures wind speed. On the other hand, a wind vein is used to determine the direction of the wind.
Name some weather instrument and each meaning?
Anemometer: measures wind speed. Barometer: measures atmospheric pressure. Hygrometer: measures humidity. Thermometer: measures temperature.
Why were speed boats invented?
Because people did not want to have to travel on huge ships. Also because ships are quite slow so people wanted to get around quicker
What instrument do you use to collect data for wind speed?
An anemometer is the instrument typically used to collect data for wind speed. It measures the speed of the wind by capturing the rate at which it moves over the device's sensors.
What are fast speed boats made of?
Fast speed boats are made of materials that are used to make fast speed boats.
What instrument shows how fast an object moves?
A speedometer is an instrument that measures the speed at which an object is moving. It typically displays the speed in units such as kilometers per hour or miles per hour.
