Overview

Engineering reference data for Toluene Thermal Properties in thermodynamics.

Key Formulas

First Law

$\Delta U = Q - W$

Energy is conserved — heat added minus work done.

Ideal Gas Law

$PV = nRT$

Relates pressure, volume, and temperature of an ideal gas.

Heat Transfer

$Q = mc\Delta T$

Sensible heat transfer.

Carnot Efficiency

$\eta = 1 - T_C/T_H$

Maximum efficiency between two temperatures.

Unit Conversions

The following conversion factors relate the SI units used in the table to other common engineering units:

Density: $1\ \text{kg/m}^3 = 0.0624\ \text{lb/ft}^3$
Specific Heat: $1\ \text{kJ/(kg·K)} = 0.2389\ \text{Btu/(lbm·°F)}$
Thermal Conductivity: $1\ \text{W/(m·K)} = 6.935\ \text{(Btu·in)/(ft}^2\text{·h·°F)}$
Dynamic Viscosity: $1\ \text{Pa·s} = 10\ \text{P (Poise)} = 10^3\ \text{cP} = 0.1020\ \text{kp·s/m}^2 = 0.6721\ \text{lb/(ft·s)}$

Note: The dynamic viscosity values in the table are presented in millipascal-seconds (mPa·s), which is equivalent to centipoise (cP).
