In free vortex what does it mean " non-trivial component of velocity vector is tangential"? I know only the tangential component of velocity exists in free vortex flow, so what happens at the eye of the vortex ( what happens to vorticity and streamlines to be specific)?

There is only 1 component

Actually I wanted to understand why degree of freedom is 1 in the wet region ?? I know by the Gibbs formula it comes 1 but to locate certain point inside the dome we need to know two properties ( eg- pressure and dryness fraction) ? How can we define the state by just one intensive property?

When water converts to steam while boiling a vapour dome can be formed, what is the degree of freedom inside this vapour dome and on the saturated points?

Ok, thanks any way for your tine

In this you considered a control volume and you are trying to calculate what are the forces that are acting on the fluid in the control volume. On the right side the pressure is exerted on the control volume by atmosphere (or the surrounding fluid)

If you are mechanical engineer then go for gere and timoshenko

Now I am more confused. What is perfect gas?

I am confused after reading. I don't know what it is trying to say.

You have given the characterstics of ideal gas, they are true but I needed how can we differentiate between ideal and perfect gas? I know one of the difference, it is that in ideal gases specific heat vary with temperature but in perfect gas specific heat is constant. I wanted to know more about it.

I haven't got the difference between ideal gas and perfect gas?

I want to know about it used in engineering

What is difference between perfect gas and ideal gas?

Why specific heat of solids and liquids doesn't change with change in temperature?

I have a just simple question why theories of faliure was developed for 2-D and 3-D failure??
