An air dryer is used to dry wet coal at a rate of 10,000 tons per day. Wet coal feed has 24 percent by mass of water when it enters and 4 percent when it exits. The hot air used to dry the wet coal is heated to 40°C for the dry bulb and 16°C for the wet bulb. At 30°C, the moist air exits the dryer with a relative humidity of 40%. Calculate the dry amount of air in m3/h at STP. (Use psychrometric chart)

The desired final conditions of the air in the room are 22 °C and 65% relative humidity. To achieve these conditions, outdoor air at 10 °C and 40% relative humidity is firstly heated to 18 °C and then humidified by steam injection. For an airflow rate of 50 m3/min, determine the rate of heat supplied and the mass flow rate of steam required for humidification. Make use of psychrometric charts.
Saturated ambient air with a db-temperature of 5°C and a mass flow rate of 0.9 kg/s is divided into two streams. One stream passes through a heating section and leaves it with a relative humidity of 25%. The conditions of the other stream that bypasses the heater remains unchanged. The two streams are then mixed to produce the supply air stream at 24°C. The pressure is constant at 101.3 kPa. -Determine the partial pressure of water vapor of the heated air in kPa.-The heat input by the heating coil in kW.-The mass flow of air through the bypass section in kg/s.
Ambient air enters a cooling coil at 24°C db-temperature and 50% relative humidity with a dry air mass flow rate of 0.9 kg/s.

what is the reason that someone can feel comfortable in a room that consists of 20oC drybulb temperature and a wet bulb temperature of 15oC ? explain with some calculation if possible (a detailed answer will be appreciated )
A cooling tower of a centralized air conditioning system handles 5,000 m³/h of water which enters the tower at 40°C. The cooled water leaves the tower at 28°C. The drift loss is 0.1% while the blowdown is 0.4%. The water make-up is 150 m³/h at 30°C. The air blown through the tower enters at 25°C and has a relative humidity of 70%. The air leaves the tower at 35°C with a relative humidity of 95%. Calculate the volume of air, in m³/h at ambient conditions that the forced draft fan of the cooling tower handles.

Atmospheric air, which is a mixture of dry air and water vapour, is supplied into ducting with a cooling coil. Initially it has a relative humidity of 0.57, volumetric flow rate of 0.72 mis and temperature of 17°C. The atmospheric air is then passed over a cooling coil such that the temperature drops to 6°C. As this is below the dew point, the water vapour condensates after cooling coll and the air leaves in a saturated state. Assuming the barometric pressure of atmosphenic air to be 1.01325 bar, determine the folowing quantities in question parts () to (vi): (1) Partial pressure of water vapour in the air and water vapour mixture entering, Pul
The small business uses a forced-draught cooling tower for cooling the water of its refrigeration and air conditioning systems. The fan power input is 3 kW. The air enters the cooling tower at 17.5 C and a relative humidity of 50 %. The water from the steam plant enters at 54C and is sprayed into the tower at a rate of 10 kg/s. The water leaving the tower is at a temperature of 25 C. The air leaves the tower at 35C and is saturated. Assume that the whole process occurs at a constant pressure of 85 kPa.
