If the pressure is 180 pounds per square inch [psi], what is the pressure in units of feet of water [ft H2O]?

On April​ 20, 2010, the DeepWater Horizon oil drilling operation​ exploded, causing the largest marine oil spill ever recorded. When estimating the volume of an oil​ spill, if there are traces of color in the oil​ slick, it is estimated at 150 nanometers​[nm] thick and a ratio of 1.4 liters per hectare​[L/ha​]. What is this ratio in gallons per square kilometer [gal/km2​]? The ratio is ___ gal/km2.

In July of 2020​, NASA launched a rover to Mars called Perseverance. The mass of the rover when launched on Earth was 2260 ​pound-mass ​[lbm​]. What was the weight of Perseverance on Mars in units of​ pound-force ​[lbf​]? The acceleration due to gravity on Mars is 3.71 meters per second squared ​[m/s2​].The weight on Mars was ____ lbf.

Given the figure, if the tensile stress on the rod is 32.6 [kPa], what is the mass of the block?

If the bottom pressure is 1.27 [Kg/cm2.abs], find the height of the liquid with a density of 0.642 [g/cm3]. The upper side is open to the atmosphere.

A 4.5-centimeter [cm] radius cylindrical tank holds a liquefied version of a new polymeric compound for space flight to Mars. The tank is pressurized to prevent evaporation at a surface pressure of 1.38 bar [bar]. A total pressure probe located at the bottom of the tank reads 21.45 pound-force per square inch [psi]. If the specific gravity of the gel is 8.9, what is the mass of gel contained in the tank in units of kilograms [kg]? Assume acceleration due to gravity simulated on the spacecraft to be 8.4 meters per second squared [m/s]. Click the icon to view the conversion table. The mass of the gel is .02 kg. (Round your answer to two decimal places.)
