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 450 meters [m], how much total pressure units of in atmospheres [atm] must the submersible be designed to withstand? Assume the surface pressure on Titan is 146 kilopascals [kPa], the surface temperature is 93 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.Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.525 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05×103 kg/m3 a. Calculate the systolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the top (and greater) number is the systolic pressure. b. Calculate the diastolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the bottom (smaller) number is the diastolic pressure.

The density of mercury = 13.6 g/cm3.What is the value of pressure inside the bubble of radius 1cm, if the bubble is in water at a depth (H) of 1m? Assume atmospheric pressure to be 1atm, surface tension = 0.075N/m & density of water = 1000kg/m3. a) 110015 Pa b) 109985 Pa c) 26 atm d) 4 atmA meat baster consists of a squeeze bulb attached to a plastic tube. When the bulb is squeezed and released, with the open end of the tube under the surface of the basting sauce, the sauce rises in the tube to a distance h, as the drawing shows. Using 1.013 × 105 Pa for the atmospheric pressure and 1470 kg/m3 for the density of the sauce, find the absolute pressure PB in the bulb when the distance h is (a) 0.18 m and (b) 0.09 m.
