Well, I understood what you mean.My ROV would be like a enclosed capsule.
Right now I am more into finding weights of my individual parts(for our testing). I could calcualte weights of enclosed parts of defined geometry like electronic bottle...etc. But I am not able to asses same for purchased part like HPU, consisting of motor and pump.
I am having solidmodel of it from my supplier, so the (outer)Volume of it. I am trying use this volume and mulitiply this with density of sea water(1030 KG/m3) and subtract that from weight of HPU from weight of HPU in air. The number I am getting is very far from that of supplier's number(the weight of HPU in sea water).
I am doing this to cross check how accurate I can estimate weight in seawater so that might be helpful for me for some parts for which I cannot get that number from supplier.
1.I am trying to find how this buoyancy concept going to work? when some part having unevn suface(like motor), cannot displace as much water as its volume is? If it can displce as much water as its volume, I should be able to calculate atleast to closer approximation.
2. Is the volume solidworks showing is not (outer) volume that it can displace when taken into water?
Could some body clear my doubt plese.
