Answer:
The heater load =35 KJ/kg
Explanation:
Given that
At initial condition
Temperature= 15°C
RH=80%
At final condition
Temperature= 50°C
We know that in sensible heating process humidity ratio remain constant.
Now from chart
At temperature= 15°C and RH=80%
[tex]h_1=38 \frac{KJ}{kg},v=0.8 \frac{m^3}{kg}[/tex]
At temperature= 50°C
[tex]h_2=73 \frac{KJ}{kg}[/tex]
[tex]So\ the\ heater\ load =h_2-h_1[/tex]
The heater load = 73 - 38 KJ/kg
The heater load =35 KJ/kg
