Question: 11 a pipe carrying slightly pressurised water has a tapping...

Question details

1.1. A pipe carrying slightly pressurised water has a tapping taken from the centre line and a vertical length of tubing attached. Calculate the internal pressure as a gauge pressure, if the water in the tube rises to a height of 450 mm. Density of water 1000kg/m3 .(4.415kN/m2) The reading on a boiler gauge is 1 MN/m2 and the barometric pressure is 760 mm Hg (mercury). Calculate the absolute pressure. Density of mercury 13560 kg/m3 .(1.1011MN/m) 1.2. A vacuum gauge indicates 750 mm Hg and the reading on the barometer is 765 mm Hg. Determine the absolute pressure in N/ m2.(1.995kN/m2) 1.3. Determine the pressure in N/m2 exerted by a column 406 mm high of a liquid which has a density of 800 kg/m3. If the top of the column is open to atmosphere, calculate the absolute pressure at the foot of the column when the barometer reading is 760 mm Hg.(104.3kN/m2) 1.4.
