118 A bathyscape dives 8000 m below the surface in the Pacific. Atmospheric pressure is 101 kPa, and seawater density is 1.03 g/cm$^3$. Working in SI units, determine the following: (a) absolute pressure (kPa) and (b) force on a 250-mm-diameter window.
119 A fuel tank on the moon ($g = 5.32 \text{ ft/s}^2$) holds 2 m$^3$ of jet fuel (specific gravity = 0.70). Water density is 1 g/cm$^3$. Determine the fuel weight.
