Sunrise said:So this is the question I am working on as shown in the attachment.
I got stuck in the part that I highlighted, where they divided the Dynamic temperature by 1000.
WHY ?
Any help will be appreciated,
Thank you.
Stagnation pressure is a thermodynamic property that represents the total pressure of a fluid when it is brought to a standstill, or stagnation, in a process called stagnation. This is also known as total pressure or pitot pressure.
Stagnation pressure can be measured using a pitot tube, which consists of a small tube with an opening facing the flow and another opening facing perpendicular to the flow. The difference in pressure between these two openings is the stagnation pressure.
Stagnation pressure is an important concept in fluid dynamics because it represents the maximum pressure that a fluid can exert on a surface. This is useful in designing and analyzing fluid flow systems, such as in aviation and engineering.
The stagnation pressure of a fluid is affected by its velocity, density, and compressibility. Changes in any of these factors will result in a change in stagnation pressure.
Stagnation pressure and stagnation temperature are directly related to each other. As stagnation pressure increases, so does stagnation temperature, and vice versa. This relationship is described by the isentropic flow equation, which is used to calculate the properties of a fluid at a stagnation point.
