do 34 with explanation

Universal Units > Review Questions millimeters of mercury [mm Hg]. What is the gravitational acceleration of Pluto, in units of meters per second squared I m/s 12 34. 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 Iml, how much total pressure in units of atmospheres latm] must the submersible be designed to withstand? Assume the surface pressure on Titan is 147 kilopascals [kPal, the surface temperature is 94 kelvins [K], and the gravity is 1.35 meters per second squared I m/s1. The specific gravity of liquid methane is 0,415 and the specifc ravity of lqgaid ethane is 0.546. 35. Airspeed (v) is related to dynamic pressure using the following formula: Pynamic 1/2pu2. Determine the dynamic pressure, in units of pascals [Pa], for an

Explanation / Answer

It should be designed to withstand max pressure so at 400 m depth and highest density i.e pure liquid ethane

P=P0+density*acceleration gravity value at titan*height

=147000+546*1.4*400

=452760 pascal

=4.468 atm
