Liquid of density 945 kg/m is flowing through a pipe as shown in the diagram below. At point A, the speed of the fluid is 6.00 m/s, while at point B the speed is 54.0 m/s. What is the difference in pressure, P- P, between points B and A?

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

In a lab, a foot-long test tube contains gasoline (density equal to 748.9 kg/m³) and oil (density equal to 950 kg/m3). The gasoline occupies the upper half of the tube while the oil occupies the lower half of the test tube. Compute for the pressure at the bottom of the tube.A: 1950.2 N/m^2B: 118.5 N/m^2C: 890.4 N/m^2D: 2537.3 N/m^2E: none of the above

Suppose you have a 9.6 cm diameter fire hose with a 2.2 cm diameter nozzle. a.) Calculate the pressure drop due to the Bernoulli effect as water enters the nozzle from the hose at the rate of 40.0 L/s. Take 1.00 × 103 kg/m3 for the density of the water.  b.) To what maximum height, in meters, above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.)

A bucket is filled with a combination of water (density 1000 kg/m3) and oil (density 700 kg/m3). These fluids do not mix (the oil will float on top of the water). If the layer of oil is 43 cm tall, what is the pressure at the interface between the oil and the water?

A horizontal pipe carries a smoothly flowing liquid of density of 1290 kg/m³. At Locations 1 and 2 along the pipe, the diameters are dj = 6.79 cm and d2 = 2.79 cm, respectively. Is the flow speed at Location 2 higher or lower than the flow speed at Location 1? d Location 1 Location 2 d2 O higher cannot tell from the data lower The flow speed at Location 1 is 1.87 m/s. What is the pressure difference AP between Location 2 and Location 1 (including its sign)? Ignore viscosity. AP = Ра

An airplane flies on a level path. There is a pressure difference of 618 Pa between the lower and upper surfaces of the wings. The area of each wing surface is about 100 m2. The air moves below the wings at a speed of 80.5 m/s. A.)Estimate the weight of the plane. B.)Estimate the air speed above the wings. Density of air is 1.29 kg/m3.

A cylindrical disk of wood weighing 50.0 N and having a diameter of 25.0 cm floats on a liquid of density p= 0.750 g/cm3 . The cylinder of liquid is 60.0 cm high and has a diameter that is the same as that of the wood. What is the gauge pressure halfway down the liquid?

A level (horizontal) pipe contains a non-viscous, incompressible fluid with a density 1200 kg/m3 that is flowing steadily. At one position within the pipe, the pressure is 300 x 103 N/m2 and the speed of the flow is 20.0 m/s. At another position, the pressure is 200 x 103 N/m2. What is the speed of the flow at this second position?
