Pressure using Enthalpy, Internal Energy and Volume Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure = (Enthalpy-Internal Energy)/Volume
P = (H-U)/V_T
This formula uses 4 Variables

Variables Used

Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Enthalpy - (Measured in Joule) - Enthalpy is the thermodynamic quantity equivalent to the total heat content of a system.
Internal Energy - (Measured in Joule) - The internal energy of a thermodynamic system is the energy contained within it. It is the energy necessary to create or prepare the system in any given internal state.
Volume - (Measured in Cubic Meter) - Volume is the amount of space that a substance or object occupies or that is enclosed within a container.

STEP 1: Convert Input(s) to Base Unit

Enthalpy: 1.51 Kilojoule --> 1510 Joule (Check conversion here)
Internal Energy: 1.21 Kilojoule --> 1210 Joule (Check conversion here)
Volume: 63 Cubic Meter --> 63 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = (H-U)/V_T --> (1510-1210)/63

Evaluating ... ...

P = 4.76190476190476

What is Enthalpy?

Enthalpy is a property of a thermodynamic system, defined as the sum of the system's internal energy and the product of its pressure and volume. As a state function, enthalpy depends only on the final configuration of internal energy, pressure, and volume, not on the path taken to achieve it.

What is Duhem’s Theorem?

For any closed system formed from known amounts of prescribed chemical species, the equilibrium state is completely determined when any two independent variables are fixed. The two independent variables subject to specification may in general be either intensive or extensive. However, the number of independent intensive variables is given by the phase rule. Thus when F = 1, at least one of the two variables must be extensive, and when F = 0, both must be extensive.
