Nesaprotu kur auseklis redz parafīna priekšrocības?]]> khe Inženiertīkli Tue, 16 Feb 2010 19:39:05 +0200 https://building.lv/forums/99/107929/107978/_subject_#msg-107978 https://building.lv/forums/99/107929/107978/_subject_#msg-107978
Iznāk ka viens kg ūdens salidot no 50 līdz 90 grādiem var uzkrāt 40x4.19 = ~160 kJ
Bet parafīns līdzīgos apstākļos
Izkausēšanai - 150 kJ
Uzsildīšanai - 87,6 kJ

Kopā 237 kJ kas ir krietni vairāk kā ūdens.

Bet nu - tāpat - īpaši nav jēgas no parafīna SA... ]]> Ronalds_ Inženiertīkli Tue, 16 Feb 2010 15:05:00 +0200 https://building.lv/forums/99/107929/107961/_subject_#msg-107961 https://building.lv/forums/99/107929/107961/_subject_#msg-107961 Jo Inženiertīkli Tue, 16 Feb 2010 12:53:32 +0200 https://building.lv/forums/99/107929/107929/_subject_#msg-107929 https://building.lv/forums/99/107929/107929/_subject_#msg-107929 khe Inženiertīkli Tue, 16 Feb 2010 08:07:23 +0200
