80 cm tall cylinder is filled with water (Pwater = 1000 kg/m³) and oil (Poil
kg/m²) and is capped on the bottom so no fluid is flowing. It contains equal amounts
of the two fluids by weight. What is the pressure at the bottom of the cup?

2. An above ground pool is being drained using a single hose as shown in the picture
below. The hose has a circular cross-section with a diameter of 3.5 cm and runs from
the bottom of the pool, up over the side of the pool, and extends 1.0 m below the pool
where water is leaving the hose. The pool wall is 1.5 m tall and the pool is currently
filled to a depth of 1.25 m. Assume the pool is much larger than the hose so that the
depth of the pool changes very slowly.
(a) What is the speed of the water leaving the hose?
(b) What is the gauge pressure in the hose at point A?
