A stormwater pipeline transports meltwater from streets in Vsters with a salt concentration of 1.2 g / liter (K_DV). The water is led to a small watercourse that has a natural salt content of 15 mg / liter (K_VD). If the stormwater line has a flow of 2,000 liters / minute (Q_DV) and the watercourse has a flow of 1.9 m3 / second (Q_VD), what is the concentration of salt in the small watercourse (K_MIX) just after the point where the two flows (Q_MIX) meet? We assume that the salt in the stormwater pipe and in the watercourse is completely mixed, and that the salt does not react with anything, and that the system is in steady state, ie no accumulation of salt in the system. Everything that enters the system leaves the system. Start by drawing a mass balance diagram for the system. Enter the concentration K_MIX in mg / liter. What consequences can street salt have on the environment.
