1. Convert the following readings of pressure to kPa assuming that barometer reads 760 mm of Hg.

(i) 80 cm of HG

(ii) 30 cm of Hg vacuum

(iii) 1.35 m H2O gauge

(iv) 4.2 bar.

2. On a piston of 10 cm diameter a force of 1000 N is uniformly applied. Find the pressure on the piston.

3. A tube contains an oil of specific gravity 0.9 to a depth of 120 cm. Find the gauge pressure at this depth (in kN/m2).

4. A vacuum recorded in the condenser of a steam power plant is 740 mm of Hg. Find the absolute pressure in the condenser in Pa. The barometric reading is 760 mm of Hg.

5. A vessel of cylindrical shape is 50 cm in diameter and 75 cm high. It contains 4 kg of a gas. the pressure measured with manometer indicates 620 mm of Hg above atmosphere when barometer reads 760 mm of Hg. Determine:

(i) The absolute pressure of the gas in the vessel in bar.

(ii) Specific volume and density of the gas.
