An air bubble originating from an under waterdiver has a radius of 5 mm at some depth h.When the bubble reaches the surface of thewater, it has a radius of 6.3 mm.Assuming the temperature of the air in thebubble remains constant, determine the absolute pressure at this depth h. The accelerationof gravity is 9.8 m/s2.Answer in units of Pa. b. Determine the depth of the diver.Answer in units of m.

Consider a low-speed flight of the space shuttle as it is nearing a landing. If the air pressure and temperature at the nose of the shuttle are 121,590 Pa and 400K, respectively, what is the density? detailed solution pls, Thank you

Snorkels are U-shaped tubes that allow swimmers to breath while swimming just below the surface of the water (1,028 kg/m). An average human can reduce the air pressure in their lungs by 2.53 KPa, when they extend their diaphram and expand their rib cage. Answer tolerance of ±5 on the third signficant digit. a) Calculate the maximum depth a snorkeler can swim under water, while breathing through the snorkel. Number Units The U-shaped manometer shown below has one end open to the atmosphere and the other end attached to a canister of pressurized gas. Saltwater is the liquid (p = 1,025 kg/m) in the manometer which extends a height 8.21 cm above point (3). Answer tolerance of ±5 on the third signficant digit. a) Calculate the absolute pressure of the gas in the canister. Number Units (1) ha hi (2) (3)
