The weight of the displaced fluid can be found mathematically. The mass of the displaced fluid can be expressed in terms of the density and its volume, m = ρV. The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the weight of the displaced fluid can be expressed as
W = ρVg
.
What is the weight of the displaced water?

How do you find displaced water?
To find the amount of water displaced,
students should subtract the initial level of the water (60 mL) from the final level of the water
.
How do you calculate the weight of water?
To find the weight of water, start by
finding the density(1 kg/L at 39.2°) and the volume of water
. Convert the volume of water to liters and then multiply by the density to find the weight.
How can I calculate weight?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s
2
on Earth. The formula for calculating weight is
F = m × 9.8 m/s
2
, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
Is displacement the same as weight?
The displacement or displacement tonnage of
a ship is its weight
. As the term indicates, it is measured indirectly, using Archimedes’ principle, by first calculating the volume of water displaced by the ship, then converting that value into weight.
What is the specific weight of water?
A commonly used value is the specific weight of water on Earth at 4 °C (39 °F), which is 9.807 kilonewtons per cubic metre or
62.43 pounds-force per cubic foot
. The terms specific gravity, and less often specific weight, are also used for relative density.
What is the weight of water?
A cup of water weighs about 224 grams
(half a pound), per the National Institute of Standards and Technology. A liter of water weighs about 1 kilogram (2.2 pounds), according to the United States Geological Survey (USGS). A gallon of water weighs about 3.79 kilograms (8.35 pounds), per the USGS.
What is the weight of 1 gallon of water?
One US liquid gallon of fresh water weighs roughly
8.34 pounds (lb)
or 3.785 kilograms (kg) at room temperature.
How do you calculate weight and height?
Body Mass Index is a simple calculation using a person’s height and weight. The formula is
BMI = kg/m
2
where kg is a person’s weight in kilograms and m
2
is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.
What is a healthy weight?
If your BMI is
18.5 to 24.9
, it falls within the normal or Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range.
What is displacement of the ship?
The displacement of a ship, D, is defined as
the number of tones of water it displaces
. The volume of displacement, V, is the underwater volume of a ship afloat i.e. the volume below the waterline.
How do you find the displacement?
- If an object is moving with constant velocity, then.
- Displacement = velocity x time.
- If an object is moving with constant acceleration then the equation of third law of motion used to find displacement:
- S = ut + 1⁄2 at2
- S = v2−u22a.
- If v = final velocity,
- u = Initial velocity.
- s = displacement.
Is displacement the boat weight?
Boats with displacement hulls move through the water by pushing the water aside and are designed to cut through the water with very little propulsion. … If you could weigh that displaced water, you would find
it equals the weight of the boat
. That weight is the boat’s displacement.
What is the specific volume of water?
The specific volume that correlates to that density is 0.00094 m
3
/kg. Notice that the average specific volume of blood is almost identical to that of water:
0.00100 m
3
/kg
.
