1. Elements of Mechanical Engineering Combined Separating and throttling calorimeter Sunilkumar M. Patel 130990136045

2. Combined Separating and throttling calorimeter Function :- Find the Dryness fraction (x) of Steam.

3. Combined Separating and throttling calorimeter Why we use Combined Separating and throttling calorimeter . . . ? ?

4. Construction . . .

5. Calculation of dryness fraction. . . . For Separating Calorimeter x1 = Ms/Ms + Mw

6. Calculation of dryness fraction. . . . For Throttling Calorimeter Enthalpy before throttling = Enthalpy after throttling Hf1+x2Hfg1 = Hf2 +Hfg2 +Cps( Tsup – Tsat ) x2 = Hg2 +Cps( Tsup – Tsat ) – Hf1 Hfg1

7. If x is initial dryness fraction of steam Water droplet in steam sample = (1-x)(Ms + Mw) kg For separating calorimeter = (1-x1)(Ms + Mw) kg For throttling calorimeter = (1-x2)Ms kg

8. Water droplet in steam sample = water droplet removed by separating calorimeter + water droplet passed through throttling calorimeter. x=x1.x2
