In an open U-tube, the pressure of a 10.0-centimeter water column on one side is balanced by a column of a fluid on the other side that has a density equal to 1550 kg/m³. What is the height of the gasoline column? (The density of water is 1000 kg/m³). The answer must be in cm.

7) A U-tube is open to the atmosphere at bothends.Water is poured into the tube until the water columnon

the vertical sides of the U is more than10 cm deep.Then, oil with a density of 950 kg/m3 is poured intoone

side, until the column of oil is 6.0 cmtall. Howmuch higher is the top surface of the oil on that side ofthe

2) What is the pressure in a gasoline pipe with a radius of 5 cm 10meters above its intake pipe, which has a radius of 10 cm and flowsat a speed of 0.25 m/s at 1.0 atm?(Gasoline has a density of 0.68 x10^3 kg/m^3).

2 identical containers are open at the top and are connected atthe bottom via a tube of negligible volume and a valve that isclosed. Both containers are filled initially to the same height of1.00 m, one with water, the other with mercury. The valve is thenopened. Water and mercury are immiscible. Determine the fluid levelin the left container when equilibrium is reestablished.

Given:

the density of water is 1000 kg/m3

the density of mercury is 13600 kg/m3
