b) Due to hydraulic shock, the pipe ruptured resulting in release of liquid ammonia into the atmosphere. Liquid ammonia immediately flashes in the surrounding at ambient temperature, = 298 K and atmospheric pressure, Patm = 101325 Nm2. Accordingly, Тать using the Eq. (1), determine the mass flow rate of liquid ammonia, Qm through the ruptured pipe assuming a constant feed flow rate of 50 kgs-' in the pipe at 240 K and 104800 Nm2. ii) 2(P; – Patm) (1) Qm = pA,C. u² + Additional Information: Density of liquid ammonia at 240 K and 104800 Nm2 = 681.75 kgm3 Discharge coefficient for release = 0.61 Ruptured pipe release area = 0.003 m² Molecular weight of ammonia = 17 gmol Specific heat ratio of ammonia = 1.35 Gas constant = 8.314 Jmol-l K-1 Ambient temperature = 298 K Pipe length = 10 m Pipe diameter = 0.304 m
