Question

Water flows from a large tank as shown. What is the atmospheric pressure?

1) 0 Pa
2) 101.3 kPa
3) 1 atm
4) 760 mmHg

Answer 1

It represents the standard atmospheric pressure at sea level. Therefore the correct option is 2) 101.3 kPa

Step-by-step explanation:

Atmospheric pressure arises due to the weight of the air above a particular point on the Earth's surface. At sea level, where the air pressure is standard, the atmospheric pressure is approximately 101.3 kilopascals (kPa), 1 atmosphere (atm), or 760 millimeters of mercury (mmHg) as measured by a mercury barometer.

This pressure remains relatively constant under standard conditions and serves as a crucial reference point for pressure measurements in various fields, including physics, meteorology, and engineering. It's the pressure that surrounds us every day and impacts various natural phenomena and human activities.

Therefore the correct option is 2) 101.3 kPa
