PURPOSE: A test system of form discharging rate for fire extinguishing with a square shaped chamber is provided to mix water with water using for replacing foam at optimal ratio and to discharge thereof. CONSTITUTION: A test system of form discharging rate for fire extinguishing with a square shaped chamber comprises a square shaped chamber, a first pump(310), a first pressure gauge(320), an one way check valve(330), a fire extinguishing storage tank(400), a second pump(510), a first check valve(520), a flow meter(530), a mixer(600), a second pressure gauge(710), a second check valve(720), and an outlet(800). The mixer mixes water transferred through the one way check valve with the fire extinguishing solution transferred through the first check valve. The second pressure gauge measures the water pressure mixed by a mixer. The second check valve controls water transferred through the mixer to be flowed.
