EXPERIMENTAL 2

1. Sensible heating-switch on 1 kW pre-heater and print the data. Then, switch on the 0.5kW re-heater and print the data and chart. For this process, calculate the temperature rise of the air at the exit.

Sensible heat – temperature rise

 

                             

 

 

 

 

 

                                    TAd = 30.3                                   TBd = 42.2

                                    TAw = 25.4                                  TBw = 29.9

 

     Temperature rise,  Td = 42.2- 30.3 = 11.9^oC

                                   Tw = 29.9- 25.4 = 4.5^oC
