Confused about Compressed Water in Constant Pressure Process?

In summary, compressed water confusion is a phenomenon that occurs when pressure is applied to water, causing its molecules to become tightly packed and exhibit unusual properties. This type of water differs from regular water in terms of density, compressibility, and unique properties. The increased pressure on water molecules is the main cause of this confusion, and it has potential applications in various industries such as food processing and energy production. However, it is not safe for consumption due to potential impurities and health risks.

Homework Statement


In a constant pressure process ant 1 bar determine how much heat must be added to raise the temperature of 2kg of compressed water at a temp of 50C so that it become superheated steam at a temp of 200C?

u2=2659KJ/Kg

Homework Equations


W=-P(V2-V1) Q+W=U2-U1


The Attempt at a Solution



Not really sure how to work out the volumes and struggling with how to find u1 as its compressed water.

Do i find out the volumes by attaining the specific volume and multiplying by the mass

FAQ: Confused about Compressed Water in Constant Pressure Process?

What is compressed water confusion?

Compressed water confusion is a phenomenon that occurs when the pressure on water is increased to a certain level, causing the water molecules to become tightly packed and exhibit unusual properties.

How does compressed water differ from regular water?

Compressed water has a higher density and is less compressible compared to regular water. It also exhibits unique properties such as decreased freezing point and increased boiling point.

What causes compressed water confusion?

The cause of compressed water confusion is the increased pressure on water molecules, which forces them to be packed closer together and form a more ordered structure.

What are the potential applications of compressed water?

Compressed water has the potential to be used in various industries such as food processing, pharmaceuticals, and energy production. It can also be used as a solvent for certain substances and in high-pressure cleaning systems.

Is compressed water safe for consumption?

Since compressed water has a different structure and properties compared to regular water, it is not recommended for consumption. It may contain impurities and can pose potential health risks if consumed without proper treatment.
