Tower Capacity BTU/hr

Range Temperature °F

Approach Temperature °F

Entering Water95 °F

Leaving Water85 °F

Wet Bulb78 °F

Formula:

Range = T_{entering} - T_{leaving}

Calculation:

Range = 95 - 85

Result:

10.00 \text{ °F}

Formula:

Approach = T_{leaving} - T_{wet bulb}

Calculation:

Approach = 85 - 78

Result:

7.00 \text{ °F}
