Questions pertaining to thermodynamics. If you're seeing this message, it means we're having trouble loading external resources on our website.

Energy can be transferred from the system to its surroundings, or vice versa, but it can't be created or destroyed. First Law of Thermodynamics: Euniv = Esys + Esurr = 0 Thermodynamics sounds intimidating, and it can be. However, if you hone in on the most important thermodynamic formulas and equations, get comfortable converting from one unit of physical measurement to another, and become familiar with the physical constants related to thermodynamics, you’ll be at the head of the class. In the limit of low pressures and high temperatures, where the molecules of the gas move almost independently of one another, all gases obey an equation of state known as the ideal gas law: PV = nRT, where n is the number of moles of the gas and R is the universal gas constant, 8.3145 joules per K. COMPENDIUM OF EQUATIONS Unified Engineering Thermodynamics I. Equation of State: pv = RT or p = RT for a thermally perfect gas II. Expressions for Work: A. Work for a simple compressible substance W = p ext dV V 1 V 2 B. Work for a simple compressible substance undergoing a quasi-static process W = pdV V 1 V 2 Steady flow energy equation is obtained by applying the first law of thermodynamics to a steady flow system. Steady Flow Energy Equation on Mass Basis : For deriving this, we have to consider m = 1 kg/sec and all other quantities will be for per kg mass such as δW/dm and δQ/dm. Thermal equilibrium is an important concept in thermodynamics. When two systems are in thermal equilibrium, there is no net heat transfer between them.

Thermodynamics equations

Intensive properties are independent of mass. such equation is the van der Waals equation with constants based on the critical point:, P v a vbRT a P RT b P RT 64 27 8 where 2 c c c c 2 2 +-= == c ^ c f m h m p where P c 2021-01-16 I know that a polytropic process equation is often the result of an empirical fit of a P-V curve that allows one to derive some nice analytical equations for the process.

Therefore, q and w are positive in the equation ΔU=q+w because the system gains heat and gets work done on itself. Second Law of Thermodynamics Equation Mathematically, the second law of thermodynamics is represented as; ΔS univ > 0 where ΔS univ is the change in the entropy of the universe.
