Title - Pressure Measurement
Summary - The vacuum pressure is the pressure below atmospheric pressure and thus negative sign is associated with this pressure value.

Q3) An inclined manometer tube is connected to two closed tanks as shown in the figure below where !-210 cm. A gage was used to measure the pressure at the center of tank A and the reading was 60 kPa. A barometer locates near the tanks reads 72 cm of mercury. Specific weight of water is 9.81 kN/m3 and specific gravity (SG) of mercury is 13.6. a) Find the gage pressure in the center of tank B. b) Find the...
The pressure in A is 20 KPa and the pressure in B is -10KPa ( a
vacuum).

A U-tube manometer is used to measure the pressure drop of water (density=1000Kg/m3) in a pipe line, which is in excess of atmospheric pressure. The right limb of the manometer contains mercury (specific gravity=13.6) and is opened to atmosphere. The contact between water and mercury is in left limb. Determine the pressure of water in the main line, if the difference in level of mercury in the limb of U-tube is 10Cm and the free surface of mercury is in...
