# Tank Pressures and U-tube

A.) See attachment for diagram. Amounts from left to right, top to bottom are: 500mm, 460mm, S.G.=0.8, S.G.=1.05, 300mm, 300mm and Tank X is water.

Calculate difference in pressure between centers of tank X and Y.

B.) See attachment for diagram again. Amounts are: Pa=2.7kPa, 0.05m, 20mm, S.G.(Oil)=0.6, S.G.=1.4, 30mm, 10mm.

Find the distance d for the U tube.

#### Solution Preview

A.)

The fluid of SG=0.8 has column = 500 mm in left hand side limb

and in right hand side it's height = (500+460) - (300+300) = 360 mm

SG of water = 1.0

When we go up in a fluid of given SG by a height h, the pressure decreases by = (SG*1000)*9.8*h

And when we come down, the pressure ...

#### Solution Summary

The solution shows each step in the calculation of the difference in pressures in two water tanks as well as the distance of a U-tube working from diagrams provided from the asker.
