Re: [PSUBS-MAILIST] dome hatch lift force

[Øystein Skarholm <skarholm@gmail.com>]

F(N)=int.pressure(Pa)*(Area_int.hatch (m^2) Internal upward force

F(N)=ext.pressure(Pa)*(Area_out.hatch (m^2) = External downward force

 

In addition the self weight of the hatch will cintribute to downward force.

Hi psubbers,

I'm trying to calculate what the lifting force will be on the

dome in my hatch when it is just submerged; but aren't

quite sure what I have to take into consideration to calculate this. Any thoughts on this?

Thanks,  Alan
