Answer:
final pressure = 0.7 MPa
quality = 20 degree super heat.
Explanation:
Given data:
water temperature 120 degree celcius
quality[tex] x_1 = 0.33[/tex]
we know that from saturated water temperature table . for T =120 DEGREE
[tex]VF_1 = 0.001060 m^3/kg[/tex]
[tex]VG_1 = 0.89133 m^3/kg[/tex]
we know that[tex]v_1 = VF_1 + x_1 VFG_1[/tex]
= 0.001060 + 0.33(0.89133- 0.001060)
= 0.29485 m^3/kg
frinal temperature of water is [tex]T_2 = T + 65[/tex]
= 120 + 65 = 185 Degree
from saturated water temp. table
for T = 185 degree, VG = 0.17390 m^3/kg
[tex]VG < v_1 =v_2[/tex]
from super heated table by interpolation
final pressure = 0.7 MPa
quality = 20 degree super heat.
