For wet steam n=1.113.

If substituted in eqn p2/p1=(2/n+1)^(n/n-1), we get p2/p1= 0.581963802, which is approximately equal to 0.582.

Superheated or supersaturated=0.546.
Dry saturated=0.578.
Wet=0.582.

n means? Explain it.

Raju said:   8 years ago
What is the value of n when steam is wet?

Balu said:   8 years ago
The Exact answer is 0.577.

Vijay said:   9 years ago
The critical pressure ratio is 0.58 because n= 1.135 for wet steam and critical pressure formula is given above.

Raviraj said:   9 years ago
The answer is 0.577 as for wet stream n=1.135.

N is the indix for steam.
N for superheated steam is 1.135.
N for dry saturated steam is 1.3.
Then N for wet steam is?

Dheena said:   1 decade ago
What is n?

Saikumar said:   1 decade ago
Steam where most of the process occurs in the wet region: n = 1.135.

Steam super heated: n = 1.30.

Air: n = 1. 4.

Methane: n = 1.31.

Helium: n = 1.667.
