Question

In regards to a cooling tower practical, the values in the table below are what I have found from the psychometric chart but I was wondering using this how would I be able to determine the following parameters for each load case: 

  • Relative humidity of inlet air and outlet air
  • Humidity ratio of inlet and outlet air
  • Enthalpy of inlet and outlet air 
  • Specific volume of inlet and outlet air 
Inlet Outlet Inlet Outlet Inlet Outlet Absolute Humidity 9.8 Absolute Humidity 11.9 Absolute Humidity 11.1 Absolute Humidity 19.5 Absolute Humidity 11 Absolute Humidity 15.8 Enthalpy 50.3 Enthalpy 50 Enthalpy 54.7 Enthalpy 75.9 Enthalpy 52.8 Enthalpy 63.2 No load Relative Humidity 46.7 Relative Humidity 82.7 0.5 kW load Relative Humidity 52.4 Relative Humidity 87.4 1 kW load Relative Humidity 53.9 Relative Humidity 86.5 Air Density 1.121 Air Density 1.197 Air Density 1.171 Air Density 1.112 Air Density 1.123 Air Density 1.127 Vapor Pressure 1497 Vapor Pressure 1899 Vapor Pressure 1782 Vapor Pressure 2938 Vapor Pressure 1678 Vapor Pressure 2401
