What is a Process Flow
Diagram?
priyatmadi 3
PFD adalah penggambaran proses industri dalam bentuk
diagram menggunakan simbol seperti garis, lingkaran,
segiempat dsb untuk menggambarkan hubungan antara
satu peralatan dengan peralatan lain dalam proses itu.
PFD menunjukkan hubungan antara komponen-komponen
utama didalam sistem. PFD juga memberikan tabel harga
disain proses untuk komponen-komponen yang beroperasi
pada mode yang berbeda seperti, minimum, normal, dan
maksimum
