1. A U-shaped tube open to the air at both ends contains some mercury with a density of 13,600 kg/m3. A quantity of water is carefully poured into the right arm of the tube until the vertical height of the water column is 15 cm.

(a) Calculate the gauge pressure at the water-mercury interface?

(b) Calculate the vertical distance h from the top of the mercury level in the left arm to the top of the water in the right arm.

2. What is the minimum volume necessary for a chunk of ice to float in water with a 55 kg person standing on it? (Assume the person doesn't want to get wet. The density of water is 1000 kg/m3 and the density of ice is 917 kg/m3.) What mass of ice is this?

3. A shower head has 20 circular openings, each with radius 1.00 mm. The shower head is connected to a pipe of radius 0.800 cm. If the speed of water in the pipe is 3.00 m/s, what is its speed as it exits the shower head openings?
