Water flows through a pipe 25 mm in diameter at avelocity of 6 m s−1. Determine whether the flow will be laminaror turbulent assuming that the dynamic viscosity of water is 1.30× 10 −3 kgm−1s−1 and its density 1000kgm−3 . If oil of specific gravity 0.9 and dynamic viscosity 9.6 ×10−2 kg m−1s−1is pumped through the same pipe, what type of flow will occur?
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.
