Q5. (a) Explain Convergence procedure to find out the bubble point temperature of a binary vapour liquid mixture. State the assumptions made and explain the notation used clearly. (b) Give the examples of chemical process applications described by the differential difference equations. Discuss about the solution options. OR The height 'h' of a liquid in a gravity flow tank & the liquid velocity 'vleaving through the outlet of the tank are given by the following equations: dv/dt = ph-qv2, dh/dt=r-sv Explain the procedure to solve these equations for v and h by Runge-Kutta 4th order method
