While taking a shower, you notice that the shower head is made up of 44 small round openings, each with a radius of 2.00 mm. You also determine that it takes 5.00 s for the shower to completely fill a 1.00-liter container you hold in the water stream. The water for the shower is pumped by a pump that is 5.50 m below the level of the shower head. The pump maintains an absolute pressure of 1.50 atm. Use g = 10 m/s2, and assume that 1 atmosphere is 1.0  105 Pa. (a) At what speed does the water emerge from the shower head? (b) What is the speed of the water in the pipe connected to the pump? (c) What is the cross-sectional area of the pipe connected to the pump?

The four tires of an automobile are inflated to a gauge pressure of 1.9 x 105 Pa. Each tire has an area of 0.024 m² in contact with the ground. Determine the weight of the automobile. N

Blood pressure is measured when the blood is pumping (systolic) and when the heart is resting (diastolic). When pressure readings are given, the systolic is given first, and healthy blood pressure is around 120 over 80 mm Hg. Recall the density of mercury is 13.6 × 103 kg/m3. a. Suppose you have a blood pressure reading of 116 over 82 mm Hg. What is your systolic pressure, in newtons per meter squared?  b. Suppose you have a blood pressure reading of 116 over 82 mm Hg. What is your diastolic pressure, in newtons per meter squared?

The drawing shows an intravenous feeding. With the distance shown, nutrient solution (p = 1020 kg/m³) can just barely enter the blood in the vein. What is the gauge pressure of the venous blood? Express your answer in millimeters of mercury. Atmospheric pressure 0.610 m Number i Units

A waste management company handles large dumpsters of construction debris. The sorting process starts by downloading the dumpster from the transport truck and then dumping its contents into a large hopper as shown below. The waste management plant uses a hydraulic cylinder arrangement to tilt the dumpster to the point that the force of gravity will empty the contents. The plant operator activates an electric pump that pumps hydraulic oil into the input piston at an absolute pressure of 3.40 x 10° Pa and drives the output plunger, which has a radius of 0.195 m. If the design of the dumping arrangement is such that the output plunger remains perpendicular to the floor of the dumpster, determine the torque the plunger creates about an axis at the end of the dumpster. 2427600 X N. m dumpster 6.00 m output plunger rotation axis input for hydraulic oil hopper

Question 7 of 18 You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of pw = 1.00 × 10³ kg/m³, fills the lower portion of the container to a depth of 0.200 m. The fluid that is floating on top of the water is 0.307 m deep. If the absolute pressure on the bottom of the container is 1.049 × 10° Pa, what is the density, pi, of the unknown fluid? The acceleration due to gravity is g = 9.81 m/s² and atmospheric pressure is Po = 1.013 x 10° Pa. Pi = kg/m3

A fluid with density 1200 kg/m flows through this pipe. As the first location, A, the fluid travels at 7.5 m/s and at the second location, B, the fluid travels at 11 m/s. What is the difference in pressure between the two points? O-1.9 x 10 Pa +3.8 x 103 Pa -2.5 x 104 Pa -3.9 x 10 Pa O +5.0 x 104 Pa

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?

The waste management plant uses a hydraulic cylinder arrangement to tilt the dumpster to the point that the force of gravity will empty the contents. The plant operator activates an electric pump that pumps hydraulic oil into the input piston at an absolute pressure of 2.50 x 106 Pa and drives the output plunger, which has a radius of 0.230 m. If the design of the dumping arrangement is such that the output plunger remains perpendicular to the floor of the dumpster, determine the torque the plunger creates about an axis at the end of the dumpster. Enter a number. Frect pressure to use for the pressure in the oil at the site of the input piston? According to Pascal's Law, how is the pressure in the oil at the site of the output plunger related to the pressure in the oil…
