Air flows from a large reservoir in which the pressure is 450 kPa through a convergent–divergent nozzle. A normal shock wave occurs in the diverging portion of the nozzle at a point where the nozzle area is twice the throat area. Find the Mach numbers on each side of this shock wave. If the Mach number on the exit plane of the nozzle is 0.2, find the back-pressure required to maintain the shock at this location.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
