Which among the following is a reason why we do not completely rely up

1.	Which among the following is a reason why we do not completely rely upon ground tests for analysing fluid dynamics?(a) Three-dimensional flows cannot be analysed(b) Facilities do not exist in all fight regimes(c) The output generated is not as accurate as theoretical analysis(d) Long run-timeThe question was asked during an interview for a job.My doubt is from Philosophy topic in portion Philosophy of Computational Fluid Dynamics of Computational Fluid Dynamics
Answer» The correct option is (b) Facilities do not exist in all fight regimes Explanation: Ground TEST facilities can be used to model three-dimensional flows also and even they PRODUCE accurate results in a LESS run-time. But they cannot be used to test all flight regimes as they want artificial set-up for EVERY SINGLE property of the flow.
