An incompressible fluid is flowing through a vertical pipe with a constriction. The wide section is 2.00 cm in diameter and is at the top of the pipe. The pressure of the fluid in the wide section at the top is 200 kPa. The velocity of the fluid in the wide section is 4.00 m/s. The narrow section is located 2.00 m below the wide section. What is the diameter of the narrow section, if the pressure of the fluid...

Water is flowing through a horizontal pipe with an inside diameter of 8.00cm. The pipe narrows to an inside diameter of 3.75cm. Assume the water is an ideal incompressible fluid. What is the velocity of the fluid initially, v_1 (when It is flowing in the 8.00cm diameter section) if the velocity of the water in the narrow part of the pipe is measured at V_2 = 27m/s? If the initial pressure is known to be 670 kPa what is the...
