Transcribed Image Text:18. Figure below shows an open water manometer for the measurement of the
pressure of a pipeline in Saudi Arabia containing oil (S.G. 0.90). The density of
water is 1000kgm/m³. For the readings given, determine the pressure at point x
if the barometric pressure is 100 KPa.

19. In an airport, the ground control reports an atmospheric reading of 750 mm
Hgabs while a pilot of an airplane reports a barometric reading of 680 mm
Hgabs. Calculate the altitude of the airplane from ground level if the average air
density is 1.20 kgm/m³ and local g= 9.81 m/s.
20. A submarine is cruising at a depth of 280 m in sea water. The average local
gravity is 9.70 m/s² and the average density of the seawater is 1.03 x
10 kgm/m³. The inside of the submarine is pressurized to atmospheric
pressure. Compute the pressure difference across the hull in KPa.
