The air is cooled and dehumidified by the countercurrent contact of water in a packed tower. Tower, etc

designed with the following conditions

The dry bulb temperature of the inlet air is $28$ C

The wet bulb temperature of the inlet air is $25$ C

Inlet air flow rate $00$ kg$/$h dry air

The inlet water temperature is $10$ C

Outlet water temperature $18$ Ch

Determine the humidity, relative humidity, dew point, enthalpy of the incoming air

What is the maximum water speed that can be used according to the above plan assuming the tower is very high
