Formulas Termodinámica

Termodinamica                                Calor

((P₁V₁)/T)=((P₂V₂)/T)                          Q=m·C_e·Δt

(P₁/T₁)=(P₂/T₂)                                  Q=m·L_v

Procesos                                          Q=m·L_p

Isobatic-->p=cte-->W=P·ΔV              ΔU=m·C_e·Δt

Isocor---->V=cte-->W=O                  Q=ΔU+W

Isotermic->T=cte-->W=(nRT)ln(V₂/V₁)=(P₁V₁)ln(V₂/V₁)

Adiabatic->P₁V₁=P₂V₂                    (F=P·A)

                1bar=10⁵Pa|1atm=101325Pa

                1L=10^-3m³|1mol gas=58g

Moment d'inercia                         Esforç unitari

Ec=½·w²·I                                     σ=F/Δ_o

Placa circular                                 Allargament unitari

l_x=½·m·R²    l_y=l_z=¼·m·R²            ε=ΔL/L_o

Esfera                                           Modul elastic

V=4/3·Π·R³  l_x=l_y=l_z=2/5·m·R²      E=σ/ε
