The area of cross-section of a large tank is 0.5 m20.5 \mathrm{~m}^2. It has an opening near the bottom having area of cross-section 1 cm21 \mathrm{~cm}^2. A load of 20 kg20 \mathrm{~kg} is applied on the water at the top. Find the velocity of the water coming out of the opening at the time when the height of water level is 50 cm50 \mathrm{~cm} above the bottom. (approx.) (Take g=10 m/s2g=10 \mathrm{~m} / \mathrm{s}^2)
View answer and explanation
Correct option: A
3.28 m/s3.28 \mathrm{~m} / \mathrm{s}
The correct answer is A (3.28 m/s3.28 \mathrm{~m} / \mathrm{s}) because it is calculated using Bernoulli's equation, considering the pressure due to the applied load and the height of the water.
