I'm having some slight difficulties in calculating the delta-v in a hohmann transfer equation. I used the equation from wikipedia (which i hope is correct) but whenever i replace the variables i get an extremly small delta-v, is this normal???

[tex]\Delta[/tex]v=[tex]\sqrt{}(\mu/r1)[/tex]*([tex]\sqrt{}(2*r2/(r1+r2)[/tex]-1))

r1=6374000 meters

r2=405500000 meters

[tex]\mu=9.814[/tex]

my final result was 0.00122149m/s

it seems like a really small number, is this right or i'm i doing something really wrong?

i attached an excel sheet to show you my work.

thanks in advance
