For the shown inverted manometer, all fluids are at 20°C. If P, - P, = 130 kPa, what must the height y be? Meriam red oil SG = 0.83 0.25 m Water Mercury A SG = 13.6 0.4 m

Q: A pipe carries an oil of specific gravity 0.8 with pressure 19.62 kPa. The pipe is 3.5 m above datum…

A: Piezometric head is given by H=Pγoil+zz=datum headPγoil=pressure head

Principles of Seepage

In hydrology, when water flows down in a pore or crack of unsaturated soil due to gravity, the deep layer of soil is called seepage. It is the slow movement of water in the soil layer. Seepage is mainly found near hydraulic structures and is responsible for the stability of earthen-type hydraulic structures.
