Quiz 3 ( pressure at a point inside a liquid - U shaped tube )
U shaped tube with irregular cross-sectional area is filled with oil then gasoline was added such that the height of oil above the separating surface becomes 3 cm and the height of gasoline becomes 5 cm if the density of oil is 800 kg/m3 then the density of gasoline is
600
700
500
480
If the height of the atmosphere is 8.4 Km calculate the pressure on airplane at height 2 Km above the ground given that the density of air is 1.2 Kg/m3
76800 N/m2
76 N / m2
738
768
A u shape tube with cross sectional area 10 cm2 was filled was water up to its half then Acetone was added from one side given that the density of acetone was 750 kg/m3 and the height of water above the separating surface was 3 cm find the mass of acetone
0.03 Kg
3000 Kg
0.6 Kg
60000 Kg
From the oppossite graph the pressure is equal at the two brunches in which level
H1
H2
H3
All of them
20 cm
10 cm
100 cm
50 cm
