Mayeso a Hydrostatic
Kutalika kwa chitoliro chilichonse chidzayesedwa ndi wopanga mphamvu zomwe zimapanga pakhoma la papaitoni zosakwana 60% ya ocheperako pa kutentha kwa firiji. Kupanikizika kudzatsimikizika ndi equation iyi:
P = 2st / d
Mitundu yovomerezeka yolemera ndi miyeso
Kutalika kwa chitoliro chilichonse chidzalemedwa mosiyana ndi kulemera kwake sikusintha kuposa 10% kapena 5.5% pansi pa kulemera kwake, kuwerengetsa kutalika kwake ndi kulemera kwake kutalika.
Kunja sikusiya kusiyanasiyana kuposa ± 1% kuchokera ku mainchesi omwe ali kunja.
Makulidwe a khoma nthawi iliyonse sadzapitilira 12,5% pansi pa khoma lotchulidwa.
Utali
Kutalika Kwachimodzimodzi: 16 mpaka 25ft (4.88 mpaka 7.62m)
Kutalika kawiri kawiri: kupitirira 25ft mpaka 3ft (7.62 ku 10,67m)
Kutalika kwa yunifolomu: Veriation yovomerezeka ± 1in
Mathero
Zitoma zitoma zidzaperekedwa ndi mathanthwe, ndipo zowotcha kumapeto zidzachotsedwa
Pamene chitoliro chikasokonekera kukhala bevel chimatha, ngodya lidzakhala 30 mpaka 35 digiri
