Explanation According to Bernoulli’s principle, sum total of air pressure and gauge pressure will be equal to the sum of atmospheric pressure at the opening of tap plus the pressure due to the water flow. P air + ρ g h = P atm + 1 2 ρ v hole 2 Here, P air is the air pressure at the top, ρ is the density of water, g is the gravitational acceleration, h is the depth of water, P atm is the standard atmospheric pressure, v hole is the speed of water through the hole. Conclusion: Substitute 186 kPa for P air , 9.8 m / s 2 for g , 10 3 kg / m 3 for ρ , 2.68 m for h , and 10 5 Pa for P atm in the above equation to find v hole . 186 kPa ( 10 3 Pa 1 kPa ) + ( 10 3 kg / m 3 ) ( 9
