Process Equipment and Plant Design A perforated plate has holes of diameter dh arranged in a pitch ph. Each hole has a tube of I.D. dt passing through it. The ligament efficiency is given by (ph - dt)/ph (ph - dh)/ph (ph - dh)/dh (ph - dh . dt/2)/ph (ph - dt)/ph (ph - dh)/ph (ph - dh)/dh (ph - dh . dt/2)/ph ANSWER DOWNLOAD EXAMIANS APP
