Is There a Connection Between Pressure, Temperature, and Velocity in Liquids?

AI Thread Summary
There is no direct equivalent to the ideal gas law for liquids due to their complex molecular interactions, which differ significantly from gases. The relationship between pressure, volume, and temperature in liquids is influenced by the incompressibility of fluids, making them more complex to analyze. Unlike gases, where molecules can be treated as non-interacting points, liquids require consideration of molecular interactions. The discussion emphasizes that pressure and temperature in liquids cannot be simplified in the same way as in gases. Therefore, the ideal gas law does not apply to liquids.

Is there a relation between pressure/velocity and temperature for liquids. Something like the ideal gas law for fluids in general?
 
Engineering news on Phys.org
Do you mean pressure/volume or pressure/(sound)velocity?

In general fluids are more complex. In an ideal gas you assume that the molecules never touch and so it's just Newtonian mechanics of perfect points moving around. With a liquid all the properties depend on interactions between the molecules of the fluid
 
I can not assume it to be compressible fluid. So the ideal gas law is ruled out.

I mean the pressure (volume) and temperature.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
