How do you find the weight of your body in the air?

1. Given: The weight of body in air W = 150 N. Force of buoyancy, F = 30 N.
2. To Find: The weight of body in water.
3. Calculation: – The weight of body in water is calculated as: Resultant weight = Actual weight – Buoyant force. ⇒ W’ = W – F. ⇒ W’ = 150 – 30.
4. ⇒ W’ = 120 N.

How do you find the specific gravity of a submerged object?

is the density of the fluid. Submerged specific gravity is equal to the specific gravity given by the ratio of the weight of the object to the weight of the fluid) minus one.

What is the specific gravity of metal if the piece of metal weight 150 grams in air and 125 grams in water?

The specific gravity of the metal is 6.

How do you find submerged fractions?

The fraction of an object’s volume that’s submerged is given by the ratio of its average density to that of the fluid: ¯ρobj/ρfl ρ ¯ obj / ρ fl .

What is specific gravity of metal?

Specific gravity for common solids and metals like aluminum, asbestos, brass, calcium and many others. Sponsored Links. The Specific Gravity – SG – is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature.

What is the specific gravity of a body in air?

A body weighs 150 N in the air and was found to weigh 100N in the water when fully submerged. What’s the specific gravity of the body? Deliver better patient care with this online program. Learn the fundamentals of business and how to apply them in your healthcare practice. Specific gravity of body = 3.

Why does an object weigh less in water than out of water?

The upthrust on the object when immersed in water is equivalent to 20g of water. This is the difference between the weight in water and out of water. It weighs less in water because of the upthrust. Now we use Archimedes principle that tells us the upthrust on a body equals the weight of the liquid displaced.

How do you calculate buoyant force from tonnes of water?

First, convert the tonnes to kg by multiplying by 1,000 to get 10,000 kg. Then use the buoyant force equation above to get B = 10,000 · 1024 · 9.80665 = 100,518,162.5 Newtons (N) or around 100.52 MegaNewtons (MN). Example 2: If the density of water in a swimming pool is 1,000 kg/m 3…

What is the weight of a marble placed in water?

This means that 40 cc of water is displaced when a marble is placed in it. The density of water is 1g/cc so the weight of displaced water is 40g. Buoyant force is 40g thus the weight of the marble will be 100–40=60g. If the weight of water and the weight of air is given, how do you find a specific gravity?
