Mathematical Analysis of an Ideal ZED

[mrwayne]

Wayne your device has been shown mathematically not to work, if you missed it go back and look at all the threads again the information is their right in front of you, I suggest you now shut your mouth and come back in the future when you have something more than your bullshit mathematics and your empty promises.  I don't care if it's in October 2015, just get lost now,,,,,come back when you have more than your repetitive BS

I am sorry, where did you do any checking of the math?

[mrwayne]

Professionalism in the Travis sense means:

"I have something, but I won't show it."

Been there and done that - good people joined our effort.

Thanks

Can somebody translate that into English?

Honest Wayne Travis, you will find that it is very common, yea verily it is universal, for real scientists to ask for evidence, to provide evidence when asked, and to support their contentions with repeatable, fully documented experiments and reports that are vetted by peers and edited for precision and accuracy. And that is all I have ever asked of you.

Please give me an example of "my unscientific assumptions" and "slander", you ignorant buffoon.

I am surely not as smart as you,
Being higher than others is not in my nature, I respect peoples skills and respect their weakness - you exploit them for your ego.
Now, what kind of scientists troll out the actual discussion, speak over, insult researchers, talk about invisible unicorns, make fun of personal photo's...... Dr stories..........
Not good scientists..... that is for sure.
If your posts were deleted -well first - that would be a benefit to mankind - and second 80% of the threads trolling would vanish.
And no one did it to you.... so stop crying about it.
Grow up.

Mark,

It is amazing that you would choose to ignore Newton,, and then carry on that it is acceptable for you to do that.

These are the lines from Mark's spreadsheet.

State 2 R1 OD force

=cir_mm2_to_mm2*mm2_to_m2*(-ST2_R2IDPressure*Riser1ODCirArea)

State 2 R2 OD force

=cir_mm2_to_mm2*mm2_to_m2*(-ST2_R3IDPressure*Riser2ODCirArea)

State 3 R1 OD force

=-cir_mm2_to_mm2*mm2_to_m2*ST3_R2_Pressure*Riser1ODCirArea

State 3 R2 OD force

=-cir_mm2_to_mm2*mm2_to_m2*ST3_R3_Pressure*Riser2ODCirArea

Newton once said that for every action there is an equal and opposite reaction.

In State 2 there is a positive pressure between the risers, that pressure pushes up on the riser above and therefore down on the riser below, and this is what creates the uplift.

As can be seen in State 2, Mark has assigned a negative value to the pressure being exerted on the lower riser, (-ST2_R2IDPressure) this meets with Newton.

In State 3 the forces between the risers has reversed.  If you look at the State 3 formulas you will see that Mark has not reversed the direction of the reaction even tho the force direction has reversed.  (-cir_mm2_to_mm2) the "-" minus sign keeps the reactionary force in the same direction as in State 2.

He has taken a negative force reaction and turned it into a positive force reaction by not reversing the reactionary force direction.

The "-" signs at the beginning of the State 3 lines should be removed to comply with Newton and to stay consistent with the formulas for State 2 they should be.

State 3 R1 OD force

=cir_mm2_to_mm2*mm2_to_m2*(ST3_R2_Pressure*Riser1ODCirArea)

State 3 R2 OD force

=cir_mm2_to_mm2*mm2_to_m2*(ST3_R3_Pressure*Riser2ODCirArea)

Now it is easy to see that the reactionary force has been reversed with the reversed direction of the applied force.

The problem for Mark is that when this is done the risers go into a negative force when they are at the calculated lift distance.

Tom you are completely clueless.  The force convention is positive for up.  Therefore positive pressure on top of a given riser OD surface exerts a downward, IE negative force according to the sign convention.

Jeepers Mark,, it is the straws that are displacing the water,, DUH!

lets add up all that lift shall we?

State 2

0.2754432294N

State 3

0.0473567581N

-0.2645634N just from riser 3 state 3,, that is when there is only ~.05N left of those straws Mark.

ooohhh you loaded the straws with some weight,, remove the straws and lets see how high it will lift,,

Sure thing Mark,, and the lift value in your straws??  How do they compare Mark.

Did I say it will not rise past that point,, *nope*, so you are making things up again,, I said after that boundary the lift force from Riser 3 reverses,, other forces are still at work and will lift it up further.

Look at the physics.  Do the calculations and you will find that what is in the R4 spreadsheet is correct.  Do you even know what a free body diagram is?
