WebSuperheated Steam Relief Valve Sizing. Description: A safety relief valve must be sized for superheated steam in a large vessel at a set pressure of 110.4 barg for a mass flow rate of 69800 kg/hr, assuming 10% overpressure.The temperature of the steam is 420 o C, the discharge coefficient is 0.84 and the back-pressure capacity correction coefficient is 1.0. WebK-FACTOR The K-factor is a “constant” that expresses the flow performance of the sprinkler head. It is determined by the size and shape of the internal waterway and water exit orifice (bore diameter).
