Graduate Does Bernoulli's Equation Apply to Ideal Gases in a Piston-Driven System?
I am not sure if you can prove Bernoulli's Equation via the kinetic theory of gases. Bernoulli's Equation takes a "macroscopic" view, whereas kinetic theory of gases takes a more "microscopic" view and uses statistics to extrapolate the macroscopic view. With that being said, Bernoulli's...- wongdaisiu

Undergrad Questions on Bernoulli Equation: Pressure, Energy & More
Bernoulli's equation assumes, inviscid (no friction between wall and fluid, and between fluid and fluid), incompressible flow (constant density). The link that Link referenced was a modified form of Bernoulli's equation. However, the added terms are just losses based upon empirical data. I...- wongdaisiu

Undergrad What is the difference between these two works ?
Hi Variation: You might want to refer to the overall energy balance equation: dPE + dKE + dU = Q - W Now the first equation have certain assumptions, that the change in potential energy is zero (such as it is on a flat surface) and the change in internal energy is zero (no state changes, or...- wongdaisiu

How Do You Calculate the Time Ratio for Two Jumping Heights on a Trampoline?
Hi... You might want to think twice about your frame of reference. I work well positive as up and negative is down. But it looks like you work the same way as well since your acceleration is negative. That would mean that your initial location is higher than your final. No matter where...- wongdaisiu
