El ebusika Lelinye lonyaka onyaka apho imozulu ikumema ukuba unxibe iimpahla ezifudumeleyo kwaye wonwabele imihlaba egutyungelwe likhephu. Kodwa wakhe wazibuza ukuba kutheni ingabandi kangako ikhephu, okanye kutheni umoya ubetha umlozi?
Siza kuthetha ngale nto kunye nezinye izinto ezibangela umdla kweli nqaku. Fumana ngakumbi malunga neli xesha lonyaka siliqalileyo.
Kutheni umoya wenza isandi?
Kwiintsuku ezininzi ebusika-kwaye nyhani unyaka wonke - umoya unokuvuthuza ngamandla. Ngokwenza njalo, ukuba ingena kumqobo, umzekelo ungaboni, iya kuvelisa ukukhawulezisa okuncinci ukusukela kumda wokuhamba komoya xa ushukuma.
Kutheni kungabandi kangako xa kukho ikhephu?
Oku, nangona kungakhange kubonakale ngathi, kunenkcazo yesayensi, kwaye yile: amaqhekeza ekhephu, enziwe ngekristali zomkhenkce, abamba umphunga wamanzi xa esiwa, kwaye loo mphunga ujika ube ngumkhenkce. Isicatshulwa esivela kwisimo segesi (umphunga wamanzi) esiqinileyo (umkhenkce) sikhupha ubushushu.
Kutheni ubusuku obucacileyo bebusika bubanda kangaka?
Ukuba uyayithanda inzululwazi ngeenkwenkwezi, uqinisekile ukonwabela isibhakabhaka esihle sasebusika. Zicacile, zikhangeleka zicocekile,… kodwa kuyabanda ngendlela emangalisayo. Ngoba? Kuba akukho mafu. Isembozo selifu sithintela ubushushu obufunyenwe emini, imitha ye-infrared, ekutshatyalalisweni, kwaye ke, ukuba akukho mafu, imitha ilahlekile.
Ubalwa njani umoya opholileyo?
Imvakalelo yokufudumeza bubushushu okanye ubushushu esibubonayo ngaphandle kobushushu bokwenyani. Lo mahluko we-thermal phakathi kolusu kunye nokusingqongileyo kugqitywa bubumanzi bendalo, isantya kunye nolwalathiso lomoya, ubumnyama, phakathi kwabanye. (uya kufumana ulwazi oluthe kratya kwi Oku kubhaliwe). Ke, umzekelo, ukuba ithemometha ibonisa u-10ºC, isibhakabhaka sicacile kwaye akukho moya uvuthuzayo, singaziva sibanda kancinci, 7,5ºC.
Yiba nobusika obuhle 🙂.
