Coconut production in Niue copra is exported from the island. The names used in the island while presenting the coconut at one of the festivals is "Fua-alu" ("Ulu-Ola"). The coconut tree is climbed by young boys of age 8 and above, and the fruit is felled. The coconut is then sheared at the top end with a pointed rod of wood fixed on the ground. After the surface skin is removed and an opening is made to drink the coconut water contained in it. The flesh inside the coconut is then scooped out and used in cooking various dishes. The stem of the tree
Liquid entry pressure Liquid entry pressure The liquid entry pressure (LEP) of a hydrophobic membrane is the pressure that must be applied to a dry membrane so that the liquid penetrates inside the membrane. LEP with the application in membrane distillation or pervaporation can be calculated as a first parameter to indicate how wettable a membrane is toward different liquid solutions. LEP depends on many parameters, including the membrane maximum pore size, the surface tension of the liquid, the contact angle of the liquid on the membrane surface, and the geometrical structure of the membrane . In the simplest form based on the
