Water at 20 C is steadily flowing through a diverging pipe section that is inclined by an angle of 30° with respect to the horizontal (See the figure) The total testing section length is 20 m long with an initial pipe diameter of 10 mm (Section 1) and final diameter of 20 mm (Section 2). The small diameter section shows a gage pressure of 100 kPa and average flow velocity 10 m/s. Other values will be obtained by reaching complete...

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...
