Why is the diffuser throat area greater than the nozzle throat area?

Correct Answer: Rise in entropy within diffuser
In a supersonic wind tunnel, there are two throats present. One is that of the nozzle which is known as the first throat which has sonic speed with corresponding area as A*. The second throat is that of the diffuser which is always greater than the first throat because there’s an increase in entropy due to the presence of shock waves.

How is diffuser throat area At2 related to the nozzle throat area At1?

The velocity of steam leaving the nozzle (V) is given by (where K = Nozzle coefficient or nozzle efficiency and hd = Enthalpy or heat drop during expansion of steam in a nozzle)

In Arun's opinion, his weight is greater than 65 kg but leas than 72 kg. His brother does not agree with Arun and he thinks that Arun's weight is greater than 60 kg but less than 70 kg. His mother's view is that his weight cannot be greater than 68 kg. If all of them are correct in their estimation, what is the average of diferent probable weights of Arun ?

The ____ section of a nozzle or diffuser is called throat.

If the semi-divergence angle of a conical nozzle is 15°, throat diameter is 8.326 cm and exit area is 0.54 m2, determine the nozzle length.

L is older than M and taller than N. O is younger than P, older than N and shorter than Q. R is older than S, younger than N, shorter than S and taller than Q. S is older than L, M, O, P, Q, R and S is necessarily false?

Normal shock diffuser is more efficient than the oblique shock diffuser.
