Hi, I was wondering how you fellow scholars of science deal with this problem that I've been having as far as I can remember. Every time I study, I HAVE to eat at small constant time intervals, tasty, usually high calorie foods, otherwise my mind will not function properly, that is I can't...

They also have difficulties. We sometimes meet and brainstorm but progress is slow. We didn't have seminaries until this week, only laboratory doing experiments. But not too useful since the same course teacher (no assistants) explains exercises at the whiteboard and keeps saying "obviously"...

I guess I'm just trying to visualize how this all works and linked because I can't seem to solve one problem right. This transition through position vectors, trajectory, the "law of space", tangents/differentials, angles, trigonometric functions and rotations is all very confusing... Btw. is it...

Hi, Just starting to learn kinematics and the book says that from the kinematic equations of motion: x=ƒ1(t) ; y=ƒ2(t) ; z=ƒ3(t) we can "eliminate de time" from the above and get: F1(x,y,z)=0 ; F2(x,y,z)=0 -> aka. trajectory eq. their "ensemble" being 2 surfaces giving the trajectory...

Thanks for your answers, I guess the flow rate does in fact depend on more than just flow area and velocity... I'm guessing that the formula above can be applied directly only for ideal cases, no friction with pipe, between particles etc., otherwise I need to find the flow by other means.

Hi, I have a question regarding the flow rate in a pipe. According to the general rule the flow rate is: Q = v * A where Q [m3/s] v [m/s] A [m2] So according to this formula the flow rate depends only on the inner area of the pipe and the velocity of the fluid and does...
