A water tank connected with a 3-separate water pump has $700 \mathrm{-L}$ capacity. The initial amount of water in the tank is $45 \mathrm{-L}$. The first pump (p1) opens at Oth second with $7.5 \mathrm{-L} / \mathrm{s} $ water and closes after $20 t h$ second, second pump $(p 2)$ opens at 6 th second with $3 \mathrm{-L} / \mathrm{s} $ water and the third pump (p3) opens after 12 seconds later with $7.5 \mathrm{-L} / \mathrm{s} $ water. Model the system in Simulink and observe the water level at 20 seconds. a) Fill in the blanks the table according to your Simulink Model. Pump 1 \begin{tabular}{1|1|1} Step Time $=$ Initial Value $=$ & Pump2 Step Time $=\sqrt{\text { Pump3 }}$ Final Value $=$ & Initial Value $=$ \ b) What would be the amount of water (in L) after 20 seconds if there is notank capacity limit? Initial Value = \end{tabular} CS.VS.980|
