Pressure = weight density × depth
Calculate the water pressure at the bottom of the 50-m-high water tower shown in the photo.
Express your answer to two significant figures and include the appropriate units
To calculate the water pressure at the bottom of the water tower, we can use the formula:
Pressure = weight density * depth
First, we need to determine the weight density of water, which is approximately 1000 kg/m³.
Next, we can substitute the values into the formula:
Pressure = 1000 kg/m³ * 50 m
Multiplying these values, we get:
Pressure = 50,000 kg/m²
Finally, we express the answer to two significant figures and include the appropriate units:
Pressure = 5.0 x 10⁴ Pa
To calculate the water pressure at the bottom of the water tower, we can use the formula:
Pressure = weight density × depth
First, we need to determine the weight density of water, which is the weight of water per unit volume. The weight density of water is approximately 1000 kg/m^3.
Next, we need to find the depth of the water tower. The photo is not provided, so we will assume that the 50 m mentioned in the question is the depth.
Now, we can substitute the values into the formula:
Pressure = 1000 kg/m^3 × 50 m
Calculating this, we find:
Pressure = 50,000 kg/m^2
To express the answer to two significant figures, we can round the value:
Pressure = 5.0 × 10^4 kg/m^2
The appropriate unit for pressure is the pascal (Pa). So, the final answer is:
Pressure = 5.0 × 10^4 Pa (to two significant figures)
