In equilibrium the salinity of a water column of area 28
cm2 and height 82 cm tall reduces linearly from 87 g/kg
(grams of salt per kilogram of water) at the bottom to 23 g/kg at
the top.
Assuming that the density of water molecules remains constant
throughout the water column, what is mass of the salt water in the
column?

In equilibrium the salinity of a water column of area 30 cm2 and height 65 cm tall reduces linearly from 85 g/kg (grams of salt per kilogram of water) at the bottom to 22 g/kg at the top. Assuming that the density of water molecules remains constant throughout the water column, what is mass of the salt water in the column?
A) Water moves in a pipe that has a diameter of 34 cm at 1 m/s, but then the pipe reduces to a diameter of 16 cm. Find the velocity of the water in the smaller portion of the pipe. B) Water in a hose with an area of 186 mm2 moves at 4 m/s, but then you cover part of the opening of the hose with your finger, and the water shoots out faster at 26 m/s . Find...
A 4.00 cm x 4.00 cm x 4.00 cm cube of density 920 kg/m3 is floating at rest at the top of a beaker of cross sectional area 100 cm2 with 500 mL of water in it. 500 mL of oil of density 900 kg/m3 is added to the top of the beaker, and the cube is observed to float completely submerged, unevenly straddling the boundary between the oil and water. a. Draw a picture showing the beaker, layers of...
.Emergency Coolant Injection from an Accumulator Tank (8 marks) Consider an accumulator tank with a cross sectional area of A,-10m, and a height of H-6m, initially filled with 5m of water as shown in the figure. The top of the tank is closed and filled with air at an initial pressure of P, 1,101 kPa At time -Os, the water starts to discharge from an opening at the bottom of the tank with an opening area of A2 0.001m2. The...
