- A cube of unknown material is 0.200 m on each side and has a mass of 17.6 kg. It is suspended in a vat of honey (densityh=1.42 x 103 kg/m³) so that its top surface is at a depth of 2.00 m below the surface of the honey (see figure-not to scale). What is the magnitude of the buoyant force on the cube from the honey?Assume that the left side of your heart creates a pressure of 112 mm Hg by exerting a force directly on the blood over an effective area of 14.0 cm2. What force (in N) does it exert to accomplish this?You can chew through very tough objects with your incisors because they exert a large force on the small area of a pointed tooth. What pressure in Pa can you create by exerting a force of 530 N with your tooth on an area of 0.800 mm2?
- a) Determine the total force and the absolute pressure on the bottom of a swimming pool 25.0 meters by 9.5 meters, whose uniform water depth is 2.0 meters. b) what will be the pressure against the side of the pool near the bottom?Water towers store water above the level of consumers for times of heavy use, eliminating the need for high-speed pumps. How high (in m) above a user must the water level be to create a gauge pressure of 3.51 × 105 N/m²? t mWater is supplied to an office building 30.0 m high through a pipe at ground level. (a) Find the minimum pressure in the supply pipe so that water can reach the top floor of the building. (b)Suppose the pressure in the supply pipe is designed so that water can flow out through a much smaller pipe on the top floor at a speed of 5.0 m/s. Find the pressure in the larger pipe on the ground floor.
- A cubical block of wood, 10.0 cm on a side, floats at the interface between oil and water with its lower surface 1.50 cm below the interface. The density of the oil is 790 kg/m3. (a) What is the gauge pressure at the upper face of the block? (b) What is the gauge pressure at the lower face of the block? (c) What are the mass and density of the block? Oil 10.0 Wood cm 10.0 Water cm(a) What is the pressure drop (in N/m2) due to the Bernoulli effect as water goes into a 2.50 cm diameter nozzle from a 8.70 cm diameter fire hose while carrying a flow of 38.0 L/s? N/m2 (b) To what maximum height (in m) above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.) mWill the force exerted on the bottom of the tube increase if the diameter (d) of the tube increases and the height of the water column is maintained? 2. Since P = F/A, will increasing the weight of the water in the tube affect the pressure exerted on the bottom of the tube?
