An unknown immiscible liquid seeps into the bottom of an open oil tank. some measurements indicate that the depth of the unknown liquid is 1.5 m and the depth of the oil(specificweight=8.5kn/m3)floatin g on top is 5.0 m. a pressure gage connected to the bottom of the tank reads 65 kpa. what is the specific gravity of the unknown liquid?

The specific gravity of the unkown liquid is 15.

Explanation:

Gauge pressure, at the bottom of the tank in this case, can be calculated from

where and are the height of the column of oil and the unkown liquid, respectively. Writing for , we have

Relative to water, the unknow liquid specific weight is 15 times bigger, therefore this is its specific gravity as well.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
