Ângulo <strong>de</strong> <strong>repouso</strong>, <strong>atrito</strong> <strong>interno</strong> e <strong>efetivo</strong> <strong>dos</strong> grãos <strong>de</strong> café com pergaminho<<strong>br</strong> />

Silva et al.<<strong>br</strong> />

CONCLUSÕES<<strong>br</strong> />

Com os resulta<strong>dos</strong> obti<strong>dos</strong>, po<strong>de</strong>-se<<strong>br</strong> />

concluir que: os ângulos <strong>de</strong> <strong>atrito</strong> <strong>interno</strong> e <strong>de</strong><<strong>br</strong> />

<strong>repouso</strong> <strong>dos</strong> grãos <strong>de</strong> café com pergaminho <strong>de</strong><<strong>br</strong> />

ambas as varieda<strong>de</strong>s aumentam linearmente<<strong>br</strong> />

com o incremento do teor <strong>de</strong> umida<strong>de</strong> <strong>de</strong>ntro<<strong>br</strong> />

da faixa <strong>de</strong> umida<strong>de</strong> analisada, o ângulo <strong>de</strong><<strong>br</strong> />

<strong>atrito</strong> <strong>interno</strong> é superior estatisticamente ao <strong>de</strong><<strong>br</strong> />

<strong>repouso</strong> em praticamente to<strong>dos</strong> os teores <strong>de</strong><<strong>br</strong> />

umida<strong>de</strong>, não diferindo somente no menor teor<<strong>br</strong> />

<strong>de</strong> umida<strong>de</strong>, para ambas espécies.<<strong>br</strong> />
