A venturi meter with a throat diameter of 100 mm is fitted in the inclined pipeline of 200 mm diameter with oil of specific gravity 0.88 flowing upwards. The venturi meter coefficient is 0.96. Two pressure gauges are fitted at tapping points, one at the throat reads the vacuum pressure of 40 cm of mercury and the other in the inlet pipe 320 mm below the throat is 20.231 N/cm2. If the loss of head in the main and throat is 0.35 times the kinetic head of the pipe, determine 2.1 the volume flow rate of oil through the pipe 2.2 the difference in level in the two limbs of the mercury manometer if it is connected to the tapping points and connecting pipes are filled with the same oil
