Water intake through porous pipes for shrimp farming purposes can be done through the water springs, water seepage, and sea water retrieval. This study aims to calculate the discharge capabilites through porous pipe compared with the ability of porous media, pore capacity of the pipe, and the pipe full capacity in the discharge pass.

This study was conducted by calculating discharge through a porous pipe based on existing formulas, and then compare it with porous media capacity, pore capacity of the pipe, and full capacity of the pipe in the discharge pass.

Findings showed that the greater of the value of the ratio between the size of the pores with wide circumferential pipe when not perforated (Af/A), then the value of the discharge coefficient  will be smaller, while the value of discharge (Q) will be even greater. Then the amount of discharge through porous pipes are under the capacity of porous media capacity, pore pipes capacity, and orifice pipe flow capacity. Thus, it can be concluded that the discharge occured is discharge based on the porous pipe capacity formula.

Keywords: Discharge, porouspipe, porousmedia, porepipes, andorifice.
