Burn time calculation

[Warzouz]

I found how to calculate TWR and ISP (by reading the wiki)

What I don't know is how to get the duration of a burn given a TWR and the dV. It must be very simple, but I'm quite lost in the various units.

Thx.

If u are happy to use mods then "kerbal engineer" gives you this info.

If not then I can't help sorry :-(

given a TWR and the dV.

dV / (TWR * g)

@Vetrox : I already use KER, but I would like to have tom hint without having to assemble a rocket. I did a very small excel sheet to do that. That gives me what basic design I must do.

Thanks Harry
