Problem 03 - Manometer

Problem
How high will liquid rise in the piezometers shown in the figure if the pressure at M is 68.95 kPa and the liquid is (a) water, (b) oil (sp gr 0.85), (c) mercury, (d) brine (sp gr 1.15)?

Problem 02 - Manometer

Problem
In the piezometers of the figure shown, liquid stands 1.37 m above point M. What is the pressure at M in kiloPascal if the liquid is (a) water, (b) oil (sp gr 0.90), (c) mercury, and (d) molasses (sp gr 1.5).

Manometers

Manometer is a simple and inexpensive device of measuring pressure and pressure difference. It is usually bent to form a U-tube and filled with liquid of known specific gravity. The surface of the liquid will move in proportion to changes of pressure.
