2) An outdoor air conditioning system with a temperature of 10°C and a
relative humidity of 30% receives a stable melody of 45m³ /min and
delivers it with a temperature of 25°C and a relative humidity of 60%. The
outside air is first heated to 22°C in the heating section and then hot
steam is injected into it in the humidification section. Suppose the whole
process is performed at a pressure of 100kPa. It is desirable to specify:
A) The rate of heat supply in the heating sector
B) The mass flow rate of water vapor required in the dehumidification
