Hi I was wondering if someone could help me with this question. Question 4 uploaded in picture.
Ok, so far this is what I have found
Pipe 1:
m1=2kg/s
P1=1000kpa
T1=100 C
h1=334.82kJ/kg
Pipe 2:
satliquid
T2=60 C
P2= 1000kpa
h2=291.36KJ/kg
Outlet:
sat vapor
P3=1000kpa
V=20 m/s
h3=267.97 kJ/kg
v3= 0.0202 m^3/kg
and I know that the mass in = mass out
so m1 + m2 = mout
My problem is that I don't know what to do with the velocity because I do not have area to use formula Vout=VA
Also I believe to solve the problem the formula m1*h1 + m2*h2 = m3*h3
but I have tried a variation of this and it did not work.
