Le soleil intense, une faible humidit\u00e9 et des vents forts peuvent acc\u00e9l\u00e9rer l'\u00e9vaporation, mais une baisse de cette ampleur indique clairement une fuite structurelle ou hydraulique. Il est fortement recommand\u00e9 de r\u00e9aliser imm\u00e9diatement un test du seau pour diagnostiquer la cause r\u00e9elle.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1779340793562\"><strong class=\"schema-faq-question\">Combien une piscine doit-elle s'\u00e9vaporer en 24 heures\u00a0?<\/strong> <p class=\"schema-faq-answer\">En moyenne, une piscine normale perd entre 3 et 6\u00a0mm (1\/8 \u00e0 1\/4 de pouce) d'eau par \u00e9vaporation toutes les 24\u00a0heures. Dans des conditions de microclimat extr\u00eames \u2014 air tr\u00e8s sec, forte chaleur ou vents soutenus \u2014 l'\u00e9vaporation quotidienne peut grimper jusqu'\u00e0 12\u00a0mm (1\/2 pouce), mais d\u00e9passe rarement cette valeur naturellement.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1779340805482\"><strong class=\"schema-faq-question\">Combien de BTU pour \u00e9vaporer 1 lb (environ 450\u00a0g) d'eau\u00a0?<\/strong> <p class=\"schema-faq-answer\">Il faut environ 970\u00a0BTU (British Thermal Units) d'\u00e9nergie thermique pour \u00e9vaporer 1\u00a0lb (environ 450\u00a0g) d'eau d\u00e9j\u00e0 \u00e0 sa temp\u00e9rature d'\u00e9bullition (100\u00a0\u00b0C \/ 212\u00a0\u00b0F) sous pression atmosph\u00e9rique standard. Si l'eau part de la temp\u00e9rature ambiante, une \u00e9nergie suppl\u00e9mentaire est d'abord n\u00e9cessaire pour \u00e9lever sa temp\u00e9rature avant le changement de phase (chaleur latente de vaporisation).<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1779340818957\"><strong class=\"schema-faq-question\">Une piscine peut-elle perdre un demi-pouce d'eau en deux jours en hiver\u00a0?<\/strong> <p class=\"schema-faq-answer\">Oui, tout \u00e0 fait. L'\u00e9vaporation hivernale est largement command\u00e9e par l'\u00e9cart entre l'eau ti\u00e8de de la piscine et l'air froid. Si vous chauffez votre piscine en hiver ou si des vents arctiques secs balayent la surface, le d\u00e9ficit de pression de vapeur augmente fortement, et une baisse d'environ 12\u00a0mm (1\/2 pouce) en deux jours, soit 6\u00a0mm (1\/4 de pouce) par jour, devient tout \u00e0 fait possible.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1779340831372\"><strong class=\"schema-faq-question\">Combien de temps faut-il pour \u00e9vaporer 8\u00a0oz (environ 240\u00a0ml) d'eau\u00a0?<\/strong> <p class=\"schema-faq-answer\">La dur\u00e9e d'\u00e9vaporation de 8\u00a0oz (environ 240\u00a0ml) d'eau d\u00e9pend enti\u00e8rement de la surface, de la temp\u00e9rature et du flux d'air. Dans un verre standard pos\u00e9 dans une pi\u00e8ce int\u00e9rieure typique, cela peut prendre plusieurs jours \u00e0 plus d'une semaine. En revanche, si l'eau est renvers\u00e9e \u00e0 plat sur un sol en b\u00e9ton expos\u00e9 \u00e0 un ventilateur, elle s'\u00e9vapore enti\u00e8rement en moins d'une heure.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1779340846146\"><strong class=\"schema-faq-question\">Comment savoir si ma piscine fuit ou si elle s'\u00e9vapore\u00a0?<\/strong> <p class=\"schema-faq-answer\">La m\u00e9thode la plus efficace est le \u00ab test du seau \u00bb. Remplissez un seau en plastique d'environ 19\u00a0litres (5\u00a0gallons) avec de l'eau de la piscine et placez-le sur une marche, en alignant exactement le niveau d'eau du seau sur celui de la piscine. Marquez les deux niveaux. Apr\u00e8s 24 \u00e0 48\u00a0heures, comparez les marques. Si le niveau de la piscine a baiss\u00e9 nettement plus que celui du seau, vous avez une fuite.
