Answer 1

problem 14:- Po=1.01x105 pa Pressure and debth d= 735m. P= Potsdg le=density of seawater = 1:03x163 kg/m3 = 1.018105+1.03% 18 . g=9,8 mis? * 735 x 9,8 = 7500090 pa Inward force of water at crush deblh on a circular porthole with a radius of n=0.43 m .. = P.ta? = 7520090 x 3,14% (0.437? = 43.66 *105 N Scanned with CamScanner
