- 1. A 500-liter tank initially contains 10 g of salt dissolved in 200 liters of water. Starting at to = 0, water that contains 1/4 g of salt per liter is poured into the tank at the rate of 4 liters/min and the mixture is drained from the tank at the rate of 2 liters/min. Determine the quantity Q(t) of salt in the tank at time t = 0 until the time when the tank overflows. Code a C program which determined this quantity Q(t) by using RK4 method with h = 1. Note: May use the concept of function prototypes, function definition, function call, recursion etc. in a program. 2.
