Area of hole =2.4mm2 Acceleration due to gravity =10m∕s2 To determine water leaked from tank, Using formula, v=√2gh ‌v=√2×10×5 ‌v=√100=10m∕s Now, we can determine flow water ( Q Q=v×A A=2.4mm2 =2.4×10−6m2 Q‌=10×2.4×10−6 ‌=2.4×10−5m3∕s Volume V leaked in 5 s , Q×t‌=2.4×10−5×5 ‌=1.2×10−4m3 ‌=120×10−6m3 Hence, the volume of the water leaked in 5 s through the hole is 120×10−6m.
