- Exact reducibleIn a large tank there are 1000 gallons (gal) of water with a concentration of 1 pound (lb)per gallon of a pollutant. Water with a concentration of 2.5 lb/gal flows in at a rate of 8gal/min (gallons per minute). At the same time, water flows out at the same rate throughan outlet at the bottom. (Assume that the incoming solution is perfectly mixed in the tankat all times.) When will the concentration of pollutant reach 2 lb/gal?Define the role of partial differential equations in real life. Do you have encountered some problems of multi-variables in real life for which you think partial differential equations are really important?
