You want to get water out of a tank using a small flexible tube that is inserted into the tank from above. At the other end of the tube, you suck with your mouth and water stars to flow out by itself. The length of the tube is 90.5 inches. The diameter of opening in the tube is 4 mm. The temperature of the water is 20°C. Find the average velocity at which water comes out of opening, in m/s, if the surface of water in tank is 90 cm above the free tube opening. Include the effect of viscosity. The viscosity of water at 20°C is 1x10^-3. dont provide hand writen solution

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
