Nasa is designing a mission to explore titan, the largest moon of saturn. titan has numerous hydrocarbon lakes containing a mix of liquid methane and liquid ethane in unknown proportions. as part of the mission, a small submersible vehicle will explore kraken mare, the largest of these lakes. assuming the maximum depth of kraken mare is less than 400 meters [m], how much total pressure in units of atmospheres [atm] must the submersible be designed to withstand? assume the surface pressure on titan is 147 kilopascals [kpa], the surface temperature is 94 kelvins [k], and the gravity is 1.35 meters per second squared [ m/s2]. the specific gravity of liquid methane is 0.415 and the specific gravity of liquid ethane is 0.546.

Total pressure in atmosphere  IS 4.36 atm

Explanation:

Given Data:

Depth of lake is 400 mtr

surface tension is 147 kilopascals

surface temperature  94 kelvin

Gravity = 1.35 m/s^2

specific gravity of methane(liquid) = 0.415

specific gravity of ethane(liquid) = 0.546

density of methane can be obtained as

Density of ethane can be obtained as

Total pressure in atmosphere can be obtained as

  = 441.84 kPa

 = 4.36 atm

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
