| You learn somethign everyday..........I thought that a P valve was to save having to take suit off while on a rhib/boat and that the bloke just gets his todger out and urinates but it seems that is not so.
Now one of the pics showed a tube and a bag....is this the same as an indwelling catheter and urine collection bag that gets tied to your leg? What affect would being at 30 metres have on a plassie bag with a litre of urine in it? I am sure there must be some sort of physics theory or law to give me the formula. |
