Hand written solution required

Suppose a 10,000-L completely-mixed stirred tank reactor (CSTR) is initially full of DI water (with almost zero conductivity). At time zero, a salt solution with a conductivity of 8,000 US/cm is pumped into the reactor at a flow rate of 2,000 L/hr. What would the conductivity in the effluent (and within the reactor) be after 10 hours
