Solve all please i give thumb up? Outside air at 15°C and 20% relative humidity is admitted at a volumetric rate of 15m³/min into an air conditioning system composed of a simple heating section followed by a humidification section, which must supply air at 27 °C and 65% relative humidity. The airflow temperature between the heating and humidifying sections is 22°C and the entire air conditioner operates at 70kPa. Determine, using calculations: (a) the rate of heat supply to the heating section, in kW, is ______. (b) the wet bulb temperature of the air after the heating section, in °C, is ______. (c) the mass flow rate of steam in the humidification section, in g/s, is ______.
