Abstrak

Penelitian ini bertujuan untuk menganalisis secara eksperimental kinerja menara pendingin basah paksa dengan menggunakan fill percikan berlubang miring bertingkat. Temperatur air panas diatur pada 60 oC; Packing memiliki sudut kemiringan 15o, 20o, 25o dan rasio perforasi 2,6%, yang terdiri dari lima tingkat isian pelat galvanis. Laju aliran air ± 0,0917 kg/s, lima variasi laju aliran udara adalah 0,02033, 0,02631, 0,02995, 0,03770, dan 0,04261 kg/s. Temperatur air panas masuk adalah 60 oC. Pada penelitian ini terlihat bahwasanya rasio massa air dan massa udara mempengaruhi kinerja cooling tower.
