A) Water moves in a pipe that has a diameter of 34 cm at 1 m/s, but then the pipe reduces to a diameter of 16 cm. Find the velocity of the water in the smaller portion of the pipe. B) Water in a hose with an area of 186 mm2 moves at 4 m/s, but then you cover part of the opening of the hose with your finger, and the water shoots out faster at 26 m/s . Find...
5.16. Water is flowing in a 3-cm-diameter pipe at an average velocity of Uav 2 m/s. Assuming water density of ρ-1000 kg/m 3 and viscosity μ-10-3 N s'm2, calculate the velocity at the center of the pipe, the shear τ at the wall, and the Reynolds number. Assuming laminar flow, calculate friction coefficient C and pressure drop dp/dx.

A 7.5-cm-diameter horizontal pipe gradually narrows to 5.0 cm . When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 31.0 kPa and 25.0 kPa , respectively. What is the volume rate of flow? Q= ____ m^3/s Please explain step by step.
Water at position 1 in a pipe, driven by a pressure P1 = 950 kPa flows at vi = 12.00 m/s. Position 1 is 6.00 m above the ground; i.e., yı = 6.00 m. Position 2 is15.0 m above the ground; i.e., y2 = 15.0 m. At position 2, the pressure is P2 = 167 kPa. Calculate the position 2 flow rate v2 in m/s. The density of water is given as p = 997 kg/m²
