Faculty of Engineering and Technology Chemical Engineering Department Mathematical Methods for Chemical Engineering Q1 For the equation: C y x = + 2 2 Find the orthogonal trajectories and then plot the equation and the orthogonal trajectories for different values of C. Q2 A tank initially contains 50 gallons of pure water. Starting at time t = 0 , a brine containing 2 lb of dissolved salt per gallon flows into the tank at the rate of 3 gallon per minute . The mixture is kept uniform by stirring and the well-stirred mixture simultaneously flows out of the tank at the same rate. How much salt is in tank at any time ? How much salt is present at the end of 25 minutes ? How much salt is present after a long time ? Q3 A large tank initially contains 50 gallons of brine in which there is dissolved 10 lb of salt. A brine containing 2 lb of dissolved salt per gallon flows into the tank at the rate of 5 gallon per minute . The mixture is kept uniform by stirring and the stirred mixture simultaneously flows out at the slower rate of
