The General Energy balance equation is:
∑ENin - ∑ENout + Egen = Est (in rate form - don't know how to put the dot above)
I know that Est is 0 when the system operates at Steady State Steady Flow (SSSF).
I have 2 formulas for ΔE in "Q-W = ΔE"
1) ΔE = ΔU + ΔKE + ΔPE
2) ΔE = m[h2 - h1 +(V2-V1)2/2 + g(z2-z1)]
How do I know which one to use in which scenario?
