1. Some species of whales can dive to depths of 800m. What is the total pressure they experience at this depth? (The density of sea water = 1020 kg/m, and 1 ATM =10° N/m)

4. The gauge pressure underwater is the difference between atmospheric pressure and absolute pressure. Which of these expressions yields the gauge pressure in SI units at a depth of 751 meters under water of density 1000 kg/m^3?   a. 1000 times 9.8 times 751   b. 1000 times 9.8 divided by 751

9. A liquid is flowing through a horizontal pipe whose radius is 2.22 x10-2 m. The pipe bends straight upward through a height of 9.8 m and joins another horizontal pipe whose radius is 3.82 x10-2 m. What is the speed of the liquid in the lower horizontal pipe if the pressure in both horizontal pipes is the same? x L0228) m/s

3. Given a square board of area 0.00500 m^2. A small statue of mass 400 grams is placed on the board. Which expression yields the pressure of the statue on the board in SI units?   a. 0.400 times 9.8 divided by 0.00500   b. 0.400 times 0.00500

What is the pressure in the liquid 8.3 m below the surface? The pressure at the surface of the liquid is 108 kPa, and the density of the liquid is 0.74 kg/m3. Use g = 9.8 m/s2 for the acceleration due to gravity

What is the pressure at a depth of 150 m in the ocean?  The density of seawater is 1. 03 × 10 3kg/m3.  Please express your answer in units of atm.
