In a factory, 12 gallons [gal] of a liquid need to be raised 30 feet [ft] to be loaded into a piece of equipment. During this process, the electric motor loses 700 watts [W] to heat while operating in a circuit that requires 15 amperes [A] of current and 110 volts [V]. The liquid has a total mass of 5 slugs [slugs] and the mass of the container is negligible. Determine the time required to lift the liquid in seconds [s].

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.

A truck driver was robbed while he was on his lunch break! At the first weigh station before lunch, the truck weighed 45,000 pounds-force [???][lbf]. At the second weigh station after lunch, which unfortunately reports weight in different units, the truck weighed 32.5 kips [???][kip]. The specific gravity of diesel fuel is 0.75.  What is the volume of fuel stolen in units of gallons [???][gal]?

NASA sent a probe to Saturn's moon Titan, where the acceleration due to gravity is 1.4 meters per second squared [ms2]. Titan's atmospheric pressure is 1.3 times Earth's atmospheric pressure at sea level. The probe landed in a lake of liquid methane, which has a density of 0.454 kilograms per liter [kgL]. Since the probe weighs 300 pounds-force [lbf] on Titan and has a volume of only 1.2 cubic feet [ft3], it immediately sank. It now sits 65 feet [ft] below the surface of the lake. The lake has a surface area exposed to the atmosphere of 24500 square meters [m2]. What is the total pressure exerted on the probe, in pascals [Pa]?

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

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.)
