## Experimental Calculation

### Volume of dry steam copllected after throttling: Wd

Observations:

 T (0C) P (Kpa) T1(0C) P1(KPa) H(mm of Hg) W Wd 120.5 117.0154 104.33 151.78 10 36.91 51.44 123 130.75 105.87 159.20 17.88 40.53 64.19 115.5 120.94 105 136.94 20 29.45 54.9306

Now let me perform calculation for 2nd reading.

1) Dryness fraction of separating calorimeter:

X1 Wd/(W+Wd) = 0.61

2) Pressure of superheated steam:

P2 = 101.325 + 13.6*9.81*18/1000 = 103.73 KPa

3) Specific heat of steam:

CP = 2081.6645 J/Kg

4) Sensible heat of water at pressure P (From steam table):

HW1 = 449961 Joule

5) Latent heat of wet steam entering throttling calorimeter (Steam Table):

L1 = 2237790 J/Kg

6) Total heat of dry steam at pressure P2 (Steam table):

H2 = 2655180 Joule

7) Saturation temperature at P2 (Steam table):

T2 = 99.94 0C

8) Dryness fraction from throttling calorimeter:

X2 (H2+Cp(t1-t2)-Hw1)/L1= 0.976
