A round pipe of varying diameter carries petroleum from a wellhead to a refinery. At the wellhead, the pipe's diameter is 53.5 cm and the flow speed of the petroleum is 13.1 m/s. At the refinery, the petroleum flows at 5.25 m/s. What is the volume flow rate of the petroleum along the pipe, and what is the pipe's diameter at the refinery? volume flow rate: m³/s diameter: cm

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 100 mL beaker holds 120 g of liquid. What is the liquid’s density in SI units?

Using the appropriate equations, predict the effects in each scenario. a. Vessels X and Y have the same diameter. X is 5 cm long and Y is 10 cm long. Which has the faster velocity of flow for the same fluid? b. A blood vessel has a radius of 4 cm. Vasoconstriction reduces the radius to 1 cm. In order to maintain the same flow, by what factor must pressure increase? c. The blood vessel in B above dilates from 1 cm to 4 cm. Does the flow rate increase or decrease?

Bowling balls are roughly the same size but come in a variety of weights. Given that the official radius a bowling ball should have is roughly 0.110 m, calculate the weight of the heaviest bowling ball that will float in a fluid of density 1.000 x 10° kg/m³. weight: N

Water exits a pipe with a cross-section of 5.2 m2 at a velocity of 1.5 m/s. What is the velocity at the inlet if the cross-section at the pipe inlet is 4.0 m2? 1.2 m/s 0.58 m/s 1.4 m/s 0.77 m/s

A nuclear power plant draws 3.1×106 L/min of cooling water from the ocean. If the water is drawn in through two parallel, 3.2-m-diameter pipes, what is the water speed in each pipe? Express your answer with the appropriate units.

A force of 295 N is applied to a hydraulic jack piston that is 0.026 m in diameter. The second piston that supports the load has a diameter of 0.19 m. What is the magnitude of the output force on the hydraulic jack? Ignore any difference in height between the pistons. [Area of a circle = nr² or (T1/4)d²] %3D F1 F2 A1 A2

A D1 = 0.80 in D2 = 0,04 in A syringe in the figure contains fluid of s.g. 1.05. If the plunger is pushed in steadily at 0.125 in/s, what is the exit velocity. Assume no leakage past the plunger. * 0.0317 ft/s 0.0417 ft/s 0.0517 ft/s O 0.0617 ft/s 5 If the velocity in a 12-in diameter pipe is 1.60 ft./s, what is the velocity in a 2.5-in diameter jet issuing from a nozzle attached to the pipe? * 7.805 m/s 0.7805 m/s 78.05 m/s 0.07805 m/s

A viscous fluid flows in two different pipes. Pipe 1 has a radius r1, and Pipe 2 has a radius r2. If both pipes have the same length and r1 > r2, choose the correct statement about the pressure difference of the fluid in Pipe 1 and Pipe 2 The pressure difference of the fluid is the same in Pipe 1 and Pipe 2. The fluid in Pipe 1 has larger pressure difference. It cannot be determined in which pipe the fluid has larger pressure difference. The fluid in Pipe 2 has larger pressure difference.
