Answer: for 1 is number 1
and for 2 is 3
Explanation:
Answer:
x = 0.75801 = 75.801%
T_2 = 72..78 degree F
Explanation:
From superheated R 134 a properties table
At 200 lb/in^2 and 200 degree F

steady flow energy equation is givena s



At 90 lb/in2 Tsat = 72.78 degree F

hfg = 77.345 Btu/lbm
h = hf + x hfg

solving for x we get
x = 0.75801 = 75.801%
