A closed tank has water at 5 m depth and an air pressure of 50 kPa above water. Find the efflux speed through a small hole.
Q1. A closed tank has water at 5 m depth and an air pressure of 50 kPa above water. Find the efflux speed through a small hole.
Answer: 14.1 m/s
Explanation: For a pressurized tank, v = sqrt(2gh + 2P/ρ). Here, v = sqrt(2*10*5 + 2*50000/1000) = sqrt(100 + 100) = sqrt(200) ≈ 14.1 m/s.
