Answer:
im not sure but kermeen looks like he has a good answer u can give him brainilest
Explanation:
Answer:
Enthalpy at outlet=284.44 KJ
Explanation:


We need to Find enthalpy of outlet.
Lets take the outlet mass m and outlet enthalpy h.
So from mass conservation

m=1+1.5+2 Kg/s
m=4.5 Kg/s
Now from energy conservation

By putting the values

So h=284.44 KJ
false
im not sure
but they haven't a direction
Answer:
(b)False
Explanation:
We know that specific Internal energy of gas u=
T
and specific enthalpy of gas h=
T
If we take the case of air we know that
=0.707 KJ/Kg=K ,
=1.005 KJ/Kg=K
If we take A fixed temperature T=300 K
so u=212.1 KJ/ kg ,h=301.5 KJ/kg
So we can say that specific enthaply of gas is always greater than its specific internal energy.
