Closed system energy balance equation

WebAccordingly, ΔEcycle = 0. Δ E cycle = 0. Remember that for a process or series of processes that ΔE= Q−W Δ E = Q − W must be satisfied. This is the First Law of Thermodynamics. Written for a cycle, ΔEcycle = Qcycle … WebIn formulating the energy balance equation for the open system, we must consider energy transfer involved with materials in transit. The energy balance equation for the open system is thus summation of energy balance equation for the closed system and energy transfer accompanied with materials transferring across the system boundary.
