Answer:
Explained
Explanation:
Analytical methods are used for Risk management in the system's engineering department and it is therefore, important to be familiar with it. Many processes and practices such as identifying, measuring, managing risks in engineering systems are done using these analytical methods. In all types of systems analytical methods such as analyzing and measuring are needed. It also helps in risk aversion and risk reduction by balancing risk. Also the decision making is becomes better when these methods are employed. In advanced as well as traditional systems there is a need to manage risk and these methods are always beneficial in doing that.
Answer:
A(t) = 160 - 130 e^(-t/40)
Explanation:
At the start, the tank contains A(0) = 30 g of salt.
Salt flows in at a rate of
(1 g/L) * (4 L/min) = 5 g/min
and flows out at a rate of
(A(t)/160 g/L) * (4 L/min) = A(t)/40 g/min
so that the amount of salt in the tank at time t changes according to
A'(t) = 4 - A(t)/40
Solve the ODE for A(t):
A'(t) + A(t)/40 = 4
e^(t/40) A'(t) + e^(t/40)/40 A(t) = 4e^(t/40)
(e^(t/40) A(t))' = 4e^(t/40)
e^(t/40) A(t) = 160e^(t/40) + C
A(t) = 160 + Ce^(-t/40)
Given that A(0) = 30, we find
30 = 160 + C
C = -130
so that the amount of salt in the tank at time t is
A(t) = 160 - 130 e^(-t/40)
