Pentane Density Specific Weight Temperaure Pressure

Overview

Engineering reference data for Pentane Density Specific Weight Temperaure Pressure 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.

Pentane Density and Specific Weight Data

Liquid Pentane at Equilibrium Pressure

Pentane at Various Pressures

Key Properties

Property	Value
Critical Temperature	196.6 °C (469.75 K)
Critical Pressure	33.7 bara (3.37 MPa)
Critical Density	232.0 kg/m³

The density of liquid pentane is nearly the same for all pressures up to 100 bara. For most practical purposes, the density at equilibrium (saturation) pressure can be used.
