Motor oil,with a viscosity of 0.25 N ∙ s/m2,is flowing through a tube that has a radius of 5.0 mm and is 25 cm long.The drop in pressure is 300 kPa.What is the volume of oil flowing through the tube per second?
A pressurized cylindrical tank,5.0 m in diameter,contains water that emerges from the pipe at point C with a speed of
As shown in the figure.Point A is 10 m above point B and point C is 3.0 m above point B.The area of the pipe at point B is
And the pipe narrows to an area of
At point C.Assume that the water is an ideal fluid in laminar flow.The density of water is 1000 kg/m3.The rate at which the water level is falling in the tank is closest to
Glycerin,with a viscosity of 1.5 N ∙ s/m2,is flowing with an average speed of 1.2 m/s through a tube that has a radius of 5.0 mm and is 25 cm long.What is the drop in pressure over the length of this pipe?
