A tank holds 100 gal of a salt water solution in which 4.0 lbm of salt are dissolved. Pure water runs into the tank at the rate of 5 gal/min and the salt water solution overflows at the same rate. If the mixing in the tank is adequate to keep the concentration of salt in the tank uniform at all times, how much salt (lbm) is in the tank after 50 min? Assume that the density of the salt solution is essentially the same as that of pure water.

Question
A tank holds 100 gal of a salt water solution in which 4.0 lbm of salt are dissolved. Pure water
runs into the tank at the rate of 5 gal/min and the salt water solution overflows at the same rate. If
the mixing in the tank is adequate to keep the concentration of salt in the tank uniform at all times,
how much salt (lbm) is in the tank after 50 min? Assume that the density of the salt solution is
essentially the same as that of pure water.
