The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculated using the hydrostatic equation:
P = ρgh
P = (1000 kg/m³)(9.8 m/s²)(4 m)
Answer:
P = ρgh
P = (1000 kg/m³)(9.8 m/s²)(4 m)
P = 39200 Pa
Explanation:
In the case of the water stored in a tank, the pressure at its bottom is the weight acting on a unit area of the surface where the tank is kept. To turn that into an equation: Pressure = weight/area, and weight = mass (m) * acceleration due to gravity (g). This means pressure = m * g/ area
