A tank is 8 m long, 6 m wide, 5 m high, and contains kerosene with density 820 kg/m3 to a depth of 4.5 m. (Use 9.8 m/s2 for the acceleration due to gravity.) (a) Find the hydrostatic pressure on the bottom of the tank. Pa (b) Find the hydrostatic force on the bottom of the tank. N (c) Find the hydrostatic force on one end of the tank. N

Part A: The human body typically contains 4.9 L of blood of density 1060 kg/m^3 . How many kilograms of blood are in the body? Part B: The average blood pressure is 1.30×104 Pa at the heart. What average force does the blood exert on each square centimeter of the heart? Part C: Red blood cells have a specific gravity of 5.0 and a diameter of about 7.5 μm. If they are spherical in shape (which is not quite true), what is the mass of such a cell?

An otter is swimming in the deep area of his tank at the zoo. The surface area of the otter's back is A = 0.45 m², and you may assume that his back is essentially flat. The gauge pressure of the water at the depth of the otter is P = 10500 Pa. Po- F= α 8 g k Po Enter an expression for the magnitude of the force F on the back of the otter in terms of the gauge pressure P and the atmospheric pressure ß A h m S π d j P t Solve for the magnitude of the force F, in newtons.
