What is the volume of water in an inclined pipe

Diagram: I have a tank of water T, which was filled with 2000l of water. At some point along the pipe connected to it, there is a leak, which is leaking at the rate of 400l/24 hours. Valve d and j ...

Molar volume and compressibility factor [closed]

I want to estimate the molar volume of water vapor and after that I want to calculate the steam compressibility factor $Z$ Point A: $p_A=50$ bar and temperature $623.15$ K Point B: $p_B=20$ bar ...

Work done to compress a liquid in container [closed]

Into a compressed container containing water with pressure p and volume V we want to pump additional water. What is the work done? Unlike in the ideal gas, the work cannot be simply found out using ...

Why does PV work consider total pressure instead of net pressure?

In physics, we define work as: $$W = F_{net}×d$$ However, in physical chemistry, PV work is calculated as: $$W = P×ΔV$$ Why is total pressure used instead of net pressure? For example, if a gas is ...

Typical balloon volume-pressure law

I need to find the gas pressure required to make a balloon take a given volume, knowing the gas densities and atmospheric pressure. Is there a typical law/correlation that can be used to approximate ...

How do you define volume for gases? [closed]

Straight forward question. If atoms forming a gas float far from each other, how can we assign a volume to it? if it is in a container, perhaps we'd say the atoms, or molecules, reach every corner and ...

Black hole mass

It has been taught to us that since the black holes have finite mass, their gravitational force is also finite, which totally fits. The Black hole anyhow has a singularity at it's center which is ...

Converting Gas volume to Liquid Volume

For a test setup, I need to set CO2 flowrate as 130 L/h but I do not have a flow measuring device to set it. So I made one device as mentioned below. Once I set the flowrate, I will remove containers/...

How can I compute the missing volume by looking at the pressure changes?

Disclaimer: I'm not in any shape used to deal with physics and forgive me in advance if this question is either out of scope of wrongly formulated. I have a very practical problem. I have a container ...

Can I tell whether a cycle is reversible or not by the $p$-$V$ diagram?

A thermodynamic process is reversible if the system remains in the equilibrium state throughout. That's what we are told in the book. My doubt is, though, can we judge whether a process is reversible ...

Is it possible to find the volume of a 4 dimensional object? [closed]

I know there is 4 dimensional objects due to communicating with my friend group. I never found how would you find the volume because it was off the science channel.

Determining pressure as a function of time for water filled balloon

Looking to determine pressure as a function of time for a water filled "balloon" at extremely high pressures (~90MPa) with a fixed flow rate out. This is to determine the time it takes to hit a ...

Definition of volume of a gas and Amagat's law

How would you define the volume of an (ideal) gas? I would say it is the volume of the container holding the gas (whether it is a fixed container or a flexible one like a balloon). However, ...

What is the physical meaning of divergence? [duplicate]

I want to visualize the concept of divergence of a vector field. I also have searched the web.Some says it is 1.the amount of flux per unit volume in a region around some point 2.Divergence of ...
