Zininzi iindlela zokulinganisa ubunzima be 4×8 sheet aluminiyam, ngokuxhomekeke kwizixhobo kunye nezixhobo onazo. Nazi iindlela ezintathu eziqhelekileyo:
- Isikali sokulinganisa: Eyona ndlela icacileyo yokulinganisa ubunzima bephepha le-aluminiyam kukusebenzisa isikali sokulinganisa. Beka iphepha kwisikali kwaye urekhode ubunzima obubonisiweyo. Qiniseka ukuba isikali sinomgangatho omkhulu kunobunzima bephepha.
- Ukufunyanwa kwamanzi: Enye indlela yokulinganisa ubunzima bephepha lealuminium kukusebenzisa ukufunyanwa kwamanzi. Gcwalisa isitya ngamanzi, Ukuqinisekisa ukuba inzulu ngokwaneleyo ukuba ingabinayo ngokupheleleyo iphepha. Rekhoda ivolumu yamanzi kwisitya. Iphantsi ngononophelo iphepha elisemanzini, qinisekisa ukuba ungayihluzi okanye uchithe amanye amanzi. Rekhoda ivolumu entsha yamanzi kwisitya, eziya kuthi zinyuke ngenxa yokufuduka okubangelwa yiphepha. Umahluko kwivolumu ngaphambi nasemva kokuphelisa iphepha lilingane nomthamo wephepha. Ubunzima bephepha emva koko bunokubalwa kusetyenziswa uxinzelelo lwe-aluminium, oko ikukuthi 2.7 Iigreyimitha kwisentimitha nganye.
- Ubalo: Ekugqibeleni, Ungabala ubunzima bephepha lealuminium usebenzisa ubukhulu bayo kunye nobuninzi be-aluminium. A 4×8 iphepha le-aluminium linendawo ye 32 unywo olumbhoxo (4 x 8 = 32). Phinda-phinda le nto ngobungqingqwa bephepha kwi-intshi ukuze ufumane ivolumu kwi-inchec ye-cubic. Phindaphinda ivolumu ngokuxinana kwe-aluminium (0.0975 I-lbs / i-cubic intshi) Ukufumana ubunzima bephepha kwiipawundi.
