What is the name of this specific, popular MEO orbit?
Answer: Space junk.
As PearsonArtPhoto explained in the answer to the linked question, these are upper stages of GEO launch vehicles. The perigee appears to be over Cape Canaveral (Lat 28*N) so we ...

Vis-Viva equation applied to Earth
With $r = a$ for a circle, your (correct!) equation simplifies to
$$ v = \sqrt{\frac{GM}{a}}$$
which using a different mass for the Sun than you used, gives the right answer. I used
...

Equivalent Vis-Viva equation but for acceleration
Equivalent Vis-Viva equation but for acceleration
Comments are already mostly conclusive, I'll stick my neck out and answer a bit further.
Let's see what "equivalent" might mean to the OP:
...

In circle orbit, give a delta V to a satellite, how to find final orbit altitude?
I used my Hohmann Spreadsheet inputting 600 km into periapsis for earth orbit and adjusting by trial and error the apoapsis for earth orbit. I look at the sum of the apoapsis and periapsis ...

In circle orbit, give a delta V to a satellite, how to find final orbit altitude?
Matlab's symbolic toolbox is very helpful to solve this problem. Below, I wrote expressions for $\Delta v$ from initial circular orbit to Hohmann transfer orbit and from Hohmann transfer orbit to ...

In circle orbit, give a delta V to a satellite, how to find final orbit altitude?
In addition to the great answers you have already got, beware of what happens in the extreme case!
The cost of a Hohmann transfer increases by altitude, but only up to a point. After that, the cost ...

In circle orbit, give a delta V to a satellite, how to find final orbit altitude?
A single application of all of the allotted delta V will result in an elliptical orbit with a perigee equal to the original altitude. What you want to do instead is to apply a delta V at the start and ...

In circle orbit, give a delta V to a satellite, how to find final orbit altitude?
To calculate how high your satellite will go, you forgot 1 major thing. The hohmann transfer. I am going to show you how to calculate the transfer from a 600 km circular orbit to another circular ...
