An electrical heater is a form of sensible heating process, and heats 0.1m/s of air from 15°C and 80% RH to 50°C? The barometric  pressure is 101.325 kPa. Using the psychrometric chart given, determine the heater wattage.
       
      
                
     
    
    
    
    1  answer:
            
              
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%
At  temperature= 50°C
The heater load = 73 - 38 KJ/kg
The heater load =35 KJ/kg
