(first order ordinary differential equation) a solution containing 90% by volume of alcohol (in water) runs at liter per min into a 100-liter tank of pure water where it is continually mixed. the mixture is withdrawn at the rate of 1 liter per min. the alcohol volume in the container, nis given as d, = 10-100, 200 ls] 0 we would like to predict the alcohol volume in the tank, nas a function time. use m-1 s. solve this problem using matlab/octave script
(a) what is the alcohol volume in the container using analytic approach for 0 s is 200 [s]?
(b) what is the alcohol volume in the container n), using fdm for 0 t 200 [s]?
(c) what is the alcohol volume in the container n(t), using matlab/octave built-in function, "ode45" for 0 s 200 [s]?
(d) plot the results of parts (a) to (c) in the same figure to confirm your solutions are reasonable.
(e) what is the alcohol volume in the container n(t) at the steady-state condition, i. e., what is the alcohol volume in the container atofrom the solutions from parts (a) to (c)?

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
