Thermo Iso — Engineering Equation Solver Ees Cengel

"Steady-flow compressor work" w_comp_in = h2 - h1 "kJ/kg"

This is a specialized guide focused on using specifically for the Thermodynamics problem style found in Cengel’s textbooks (e.g., Thermodynamics: An Engineering Approach ), with emphasis on Iso (Isentropic, Isothermal, Isobaric, Isochoric) processes.

"Actual (given efficiency η=0.85)" η = 0.85 η = (h1 - h2a)/(h1 - h2s) h2a = h1 - η*(h1 - h2s) W_a = h1 - h2a EES replaces table lookup: "Steady-flow compressor work" w_comp_in = h2 - h1

"Isothermal boundary work for ideal gas" W_b = m R T ln(v2/v1) "Negative if compressed" "Alternatively:" W_b = m R T ln(P1/P2) Thermodynamics: An Engineering Approach )

P1 = 3 [MPa] T1 = 400 [C] P2 = 50 [kPa] Fluid$ = 'Steam' s1 = entropy(Fluid$, P=P1, T=T1) h1 = enthalpy(Fluid$, P=P1, T=T1)

"Isentropic turbine work" W_s = h1 - h2s "kJ/kg"
