Answer

18 °C = 18 + 273.15 = 291.15 \text{ K}$

Here are the solutions to your questions:

3.2.1 Using absolute temperatures, the enthalpy at the pre-heater inlet and outlet in kJ/s

Step 1: Convert the air temperatures from Celsius to Kelvin. The pre-heater increases the air temperature from $18 \text{ °C}$ by $22 \text{ °C}$ . Inlet air temperature: $T_{air,in} = 18 °C = 18 + 273.15 = 291.15 \text{ K}$ Outlet air temperature: $T_{air,out} = 18 °C + 22 °C =
