how many kw is an airflow of 30m³/s @130°C

To determine the kilowatt (kW) value of an airflow, you need to know the specific heat capacity and the temperature difference. The specific heat capacity tells you how much energy is required to raise the temperature of a certain volume of air by a certain amount, and the temperature difference represents the change in temperature.

1. Specific Heat Capacity:
The specific heat capacity of air is approximately 1.005 kJ/kg·K.

2. Delta T (Temperature Difference):
To determine the temperature difference, you need to compare the initial temperature of the air to the final temperature. However, you've only provided the final temperature (130°C). To calculate the temperature difference, you need the initial temperature.

Once you have the temperature difference and the specific heat capacity, you can calculate the energy required to heat the air using the following formula:

Energy (in kilojoules) = Specific Heat Capacity (in kJ/kg·K) × Mass (in kg) × Delta T (in K).

To convert the energy from kilojoules (kJ) to kilowatts (kW), you need to divide the energy value by the time taken. However, you haven't provided the time duration. Consequently, we can't directly convert the energy to kilowatts without additional information.

Please provide the initial temperature or any other missing information necessary to answer your question accurately.
