Enunciat: Una màquina de vapor que extreu Qh=700 MJ de la font calenta (Th=600 ºC), fa un treball net W=300 MJ. La font freda està a Tc=120 ºC. Determineu:
a) Rendiment de Carnot (Teoric): E_c = 1 - (Tc_K / Th_K) = 1 - (393 / 873) = 0,5498 = 54,98%
b) Treball màxim: W_max = Qh * E_c = 700 * 0,5498 = 384,86 MJ
c) Rendiment real: E_r = W / Qh = 300 / 700 = 0,4285 = 42,85%
d) Treball perdut: W_i = W_max - W = 384,86 - 300 = 84,86 MJ

P.1. Explicar breument les idees principals del text i com hi apareixen relacionades. El text estableix el criteri fonamental de l'empirisme: totes les nostres idees deriven obligatòriament d'impressions prèvies.
