2.12 The liquid storage tank shown in Fig. E2.12 has two inlet streams with mass flow rates w₁ and W2 and an exit stream with flow rate w3. The cylindrical tank is 2.5 m tall and 2 m in diameter. The liquid has a density of 800 kg/m³. Normal operating procedure is to fill the tank until the liquid level reaches a nominal value of 1.75 m using constant flow rates: w₁ = 120 kg/min, w2 = 100 kg/min, and w3 = 200 kg/min. At that point, inlet flow rate W₁ is adjusted so that the level remains constant. However, on this particular day, corrosion of the tank has opened up a hole in the wall at a height of 1 m, producing a leak whose volumetric flow rate 94 (m³/min) can be approximated by 94 0.025h - 1 where his height in meters. a. If the tank was initially empty, how long did it take for the liquid level to reach the corrosion point? b. If mass flow rates W₁, W2, and W3 are kept constant indefinitely, will the tank eventually overflow? Justify your answer. W1 T h ✓ Figure E2.12 1 m աշ 94 W3
