Even in compressible flows, the term involving " ? " is often negligible; however it can occasionally be important even in nearly incompressible flows and is a matter of controversy.
32.
Note that true dynamic similitude may require matching other dimensionless numbers as well, such as the Mach number used in compressible flows, or the Froude number that governs open-channel flows.

From current EASA definitions : Indicated airspeed means the speed of an aircraft as shown on its pitot static airspeed indicator calibrated to reflect standard atmosphere adiabatic compressible flow at sea level uncorrected for airspeed system errors.

Present-day textbooks on compressible flow and gas dynamics Nonetheless, the Ph . D . dissertation of Theodor Meyer in 1908 is arguably one of the most influential in the entire field of fluid mechanics.
35.
Both bulk viscosity and dynamic viscosity need not be constant in general, they depend on density, on each other ( the viscosity is expressed in pressure ), and in compressible flows also on temperature.
36.
Much of basic gas dynamics is analytical, but in the modern era Computational fluid dynamics applies computing power to solve the otherwise-intractable nonlinear partial differential equations of compressible flow for specific geometries and flow characteristics.
37.
I would try the one for adiabatic compressible flow even though the adiabatic assumption may not jive with your request of Everything being at room temperature . talk ) 04 : 09, 12 December 2012 ( UTC)

Per compressible flow, there is little compression ( thus little heating ) until Mach . 3, about 230 MPH . Keep in mind also that moving air will speed up heat transfer away from your hands, making them feel colder.
40.
Even compressible flows of gases that vary in pressure and temperature may be measured with acceptable uncertainty by merely taking the square roots of the absolute pressure and / or temperature, depending on the purpose of the measurement and the costs of ancillary instrumentation.
