I was asking for how a turbulent wake ( past an object) differs from a laminar wake( before object) for a mach number of 0.2

Suppose a fluid passes from having laminar flow, to having a turbulent flow (like when passing after an object). How do fluid speed and fluid density change after that?

Suppose it is on the surface of the sea, for example. So, the lower part is filled with water. The upper part is filled with air.

Suppose you have a spherical cavity, with a flow of a fluid ( in particular water), entering it from one side. What will happen to this flow? Will it create turbulences? Will speed increase? Will eventual waves entering the cavity be reflected, so creating waves with bigger amplitude? Suppose...

Now I understand :)

I didn't understand what you mean sorry..could you please explain it better?

Exactly my reasoning :)

I understand now :) thanks :)

That's perfectly true, but my point was, that in 2 seconds, maybe the car won't lose so much speed ( sorry if I m too approximate, but I never had experience with design), and car would start to gain velocity very fast. But from a merely electrical point of view, if you supply current, for, say...

Hi. I'm a student of electrical engineering, and I've always been interested in the idea of electrical cars, so I came up with a question: let's suppose we want to have a normal trip with car, and then we're not interested in going so fast with it. When we are driving in this condition, it isn't...

Yes. Thanks..It s exactly what I was asking for. No losses than? Of any kind?

Is there any way to convert a continuous, aperiodic spectrum, to a discrete spectrum, in a signal? If so, would part of he energy of this signal be lost, I am this process of conversion, or would it be " distributed" amomg the various frequencies?

Anyone??

Homework Statement Hi everyone. I was trying to solve an exercise from the book Leon couch, communication systems, number 3.7 of the 6th edition. This is the statement: In a PCM binary system, the quantisation noise mustn t exceed the percentage value P of the peak power. Show that the...

that's an interesting question as well :)
