1 TEAM II Cooling Tower Analysis By: Cortez Rankin & D. Caruthers

2 Objectives Components of Cooling Tower Air Outlet Velocities and Flow Rates Air Inlet Velocities and Flow Rates Water Inlet and Outlet Data Comparison of Different Water Inlet Flow Rates

3 Water Cooling Tower

4 Balances Assuming Steady State Operation [IN = OUT] Overall Mass Balance M AO + M WO = M AI + M WI Overall Energy Balance h AO M AO + h WO M WO = h AI M AI + h WI M WI AO=Air Outlet AI=Air Inlet WO=Water OutletWI=Water Inlet

5 Portable Cooling Tower

6 Air Inlet

7 Air Outlet and Water Inlet

8 Psychrometric Chart

9 Air Inlet Data for Water Inlet Flow Rate = 5.1 (l/min) Velocity = 12.2 m/s Wet Bulb Temp. = 18 °C Dry Bulb Temp. = 25.5 °C Area = m 2 Relative Humidity = 48% Volumetric Flow Rate= m 3 /s

10 Air Inlet Data for Water Inlet Flow Rate = 10.1 (l/min) Velocity = 12.0 m/s Wet Bulb Temp. = 17 °C Dry Bulb Temp. = 25 °C Area = m 2 Relative Humidity = 45% Volumetric Flow Rate= m 3 /s

11 Air Inlet Data for Water Inlet Flow Rate = 40.3 (l/min) Velocity = 8.0 m/s Wet Bulb Temp. = 19 °C Dry Bulb Temp. = 27.5 °C Area = m 2 Relative Humidity = 45% Volumetric Flow Rate= m 3 /s

12 Outlet Velocity as a Function of Radius for Water Inlet Flow Rate = 5.1 (l/min)

13 Outlet Velocity as a Function of Radius for Water Inlet Flow Rate = 10.1 (l/min)

14 Outlet Velocity as a Function of Radius for Water Inlet Flow Rate = 40.3 (l/min)

15 Calculate Outlet Air Velocity

16 Formulas Volumetric Flow Rate = (Area)(Velocity) Mass Flow Rate = (Density)(Volumetric Flow Rate)

17 Outlet Air for Water Inlet Flow Rate = 5.1 (l/min ) Area = m 2 Volumetric Flow Rate= 1.7 m 3 /s Temp. Dry Bulb= 21 °C= Wet Bulb Temp. Enthalpy = 79 kJ/kg Dry Air

18 Outlet Air for Water Inlet Flow Rate = 10.1 (l/min ) Area = m 2 Volumetric Flow Rate= 1.6 m 3 /s Temp. Dry Bulb= 23 °C= Wet Bulb Temp. Enthalpy = 86 kJ/kg Dry Air

19 Outlet Air for Water Inlet Flow Rate = 40.3 (l/min ) Area = m 2 Volumetric Flow Rate= 1.0 m 3 /s Temp. Dry Bulb= 31°C= Wet Bulb Temp. Enthalpy = 123 kJ/kg Dry Air

20 Water Data for Water Inlet Flow Rate = 5.1 (l/min ) Inlet Temp.= 52.5 o C Outlet Temp.= 27.7 o C Temp. Change= 24.8 o C Mass Flow Rate= kg/s Tons of Cooling= 2.5

21 Water Data for Water Inlet Flow Rate = 10.1 (l/min ) Inlet Temp.= 56.3 o C Outlet Temp.= 31 o C Temp. Change= 25.3 o C Mass Flow Rate= kg/s Tons of Cooling= 5.1

22 Water Data for Water Inlet Flow Rate = 40.3 (l/min ) Inlet Temp.= 52 o C Outlet Temp.= 30.4 o C Temp. Change= 21.6 o C Mass Flow Rate= kg/s Tons of Cooling= 17

23 Admin Tower Schematic

24 Admin Cooling Tower Front (West) Inlet Dry Bulb Temp = 18 o C Wet Bulb Temp = 12 o C Area = 4.6 m 2 Air Speed = 1.4 m/s Volumetric Flow rate = 6.1 m 3 /s Density of Area = 1.2 kg/m 3 Mass flow rate = 7.3 kg/s

25 Admin Cooling Tower Front (West) Inlet Team 3 Dry Bulb Temp = 33 o C Wet Bulb Temp = 24.5 o C Area = 4.6 m 2 Air Speed = 1.6 m/s Volumetric flow rate = 7.6 m 3 /s Density of Area = 1.1 kg/m 3 Mass flow rate = 8.3 kg/s
