21. This is best expressed in terms of the compressibility 22. The attacks were all by individual aircraft using what was called the compressibility factor. 23. So, mathematical compressibility always happens in the context of data compression in programming? 24. :Another factor that sometimes needs to be considered is compressibility of the fluid. 25. Which interaction is more important depends on temperature and pressure ( see compressibility factor ). 26. In practice compressibility error is negligible below about 10, 000 feet and 200 knots. 27. These problematic phenomena appearing at or above the critical Mach number became known as compressibility . 28. The compressibility question is actually very important. 29. Compressibility refers to whether or not the flow in a problem can have a varying density.30. It has a very low compressibility .
