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 bicycle tire is fi lled with air at an absolute pressure of169.12 kPa, and the temperature inside is 30.0 °C. Supposethe valve breaks, and the air starts to exhaust out of the tireinto the atmosphere (pa = 100 kPa absolute and Ta =20.0 °C). The valve exit is 2.00 mm in diameter and is thesmallest cross-sectional area of the entire system. Frictionallosses can be ignored here; one-dimensional isentropicflow is a reasonable assumption. (a) Find the Machnumber, velocity, and temperature at the exit plane of thevalve (initially). (b) Find the initial mass flow rate out ofthe tire. (c) Estimate the velocity at the exit plane using theincompressible Bernoulli equation. How well does thisestimate agree with the “exact” answer of part (a)? Explain.
