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.

A single-stage axial flow pump with outer radius r2 =0.240 m and inner radius r1 =0.120 m is given. At a radius of r =0.090 m, absolute flow flows in from the axial direction just before the impeller inlet and relative flow flows out in the axial direction just after the impeller outlet. Assuming a flow rate Q = 0.265 m^3/s, a water density ρ = 1.000 × 103 kg/m^3, a rotation speed n = 2.4 × 10^3 rpm, and a gravitational acceleration g = 9.81 m/s^2 , and assuming that the theoretical head Hth = W/g (W: specific work) derived from Euler's law is constant at all impeller radii, answer the following questions.

. Indiana Jones needs to ascend a high-rise building. There is a large hose filled with pressurized water hanging down from the building top. He builds a square platform and mounts four 4-cm-diamter nozzles pointing down at each corner. By connecting hose branches, a water jet can be produced from each nozzle. Jones, the platform, and the nozzles have a combined mass of 150 kg. Determine the minimum water jet velocity needed to raise the system.

Q1: A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a distribution system for potable water. A completely filled and pressurized water tank was found with a small leakage (a hole 5cm in diameter) located on the sidewall of the tank, around 5 meters below the top of the tank.

Fluid Mechanics A horizontal jet of water exits a nozzle with a uniform velocity of Vj = 20 m/s and area of Aj= 3 cm^2, and strikes a flat plate that moves to the right at velocity of Vc = 15 m/s. Upon impinging the plate, the jet splits into an equal upward and downward half-jet. (i.e. A1 = A2 = 0.5Aj). Neglecting gravity and viscous forces, determine the force (in both x - and y - directions) required to keep the plate moving at a constant velocity.
