Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

liquid (density 800kg/m3, viscosity 10−3 kg/ms) has to be supplied at a mean speed of 2m/s through a pipe of diameter 12.5mm with a surface roughness equivalent to that for structural steel. What is the magnitude of the pressure gradient necessary to achieve this flow? Your answer should have a positive sign and be to the nearest 10 Pa/m. You may wish to use the Moody diagram.
Carbon dioxide at 125 °C flows over a flat plate at 0.4 m/s. If we use 3.5 x 105 as the critical Reynolds number, what will be the distance along the plate that you can expect the flow to remain laminar? What is the distance if you use the range of values given by my fluid’s textbook (Cengal and Cimbala) of 1 x 105 for ideal situations to 5 x 105 for typical engineering situations?
