Transcribed Image Text:### Heat Transfer Calculation
**Objective:**
Calculate the magnitude of the heat transfer (kJ) required to cool 55.0 liters of a liquid mixture containing 70.0 wt% acetone and 30.0% 2-methyl-1-pentanol (C₆H₁₄O) from 45.0°C to 20.0°C.
**Given Information:**
- The specific gravity of 2-methyl-1-pentanol: 0.826
- True heat capacity of 2-methyl-1-pentanol: 248.0 J/(mol °C)
**Calculations:**
1. **Estimate the required heat transfer using Kopp's rule**
This method estimates the heat capacities of both acetone and 2-methyl-1-pentanol to calculate the necessary heat transfer.
- **Result:** 1713.3 kJ
2. **Estimate the required heat transfer using the true heat capacities**
This method uses the given true heat capacities for a more accurate calculation.
- **Result:** 802.00 kJ
This example demonstrates the difference between estimating heat transfer using Kopp's rule and using true heat capacities, highlighting the importance of accurate data in chemical engineering calculations.
