You are tasked with using your lungs to produce flow at a Ma

You are tasked with using your lungs to produce flow at a Mach number greater than or equal to one and are give a converging-diverging nozzle with an area ratio of 10. The nozzle is 4 inches long and has a diameter about that of a cigar. Could you accomplish this task? Explain. (This is a trick question)

Solution

no because in a converging diverging nozzle area ratio of 10 so we cannot decide a flow of mach number because the area at initial stage get varied from input to throat and from throat to exit since the nozzle is 4 inches long and diameter about that of a cigar so we have to use any one type of nozzle that is it may be either convergent or divergent then only the flow makes possible beacause in case of convergent nozzle the cross area gets decreased from inlet to throat and in case of divergent nozzle the cross section area increases from inlet to throat.
