What are typical values for 'K' in the Ostwald model for non-Newtonian fluids?

AI Thread Summary
The discussion focuses on finding typical values for the 'K' parameter in the Ostwald model for non-Newtonian fluids, specifically for strain-hardening fluid flow. Users are seeking resources that provide tables of 'K' values for various materials, noting that the values seem to range from 1 to 10 in some sources. One referenced document indicates values between 1 and 2, which may be applicable for certain systems. The conversation highlights the need for accessible data to aid in modeling shear force on a wall. Overall, the quest for reliable 'K' values remains a key concern for those studying non-Newtonian fluid behavior.

I need to make a simple model of a strain-hardening fluid flow, basically to find shear force on a wall. I'm looking at the Ostwald model

but I can't find any values for "K" for any material. I don't really care too much what material I'm looking at, I just want to at least get an idea of what it typically looks like. Does anyone know of any resource with tables of some K values?

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
