Explain why water comes out more slowly from an upstairs tap than from a similar tap downstairs. Water from upstairs tap Water from downstairs tap

As the depth of the water increases, the pressure also increases. The depth of the water from the roof to the upstairs tap is less compared to the depth of the water from the roof to the downstairs tap. Thus, the pressure will be less in the upstairs tap. Hence, the water comes out more slowly from an upstairs tap than from a tap downstairs.
