Find an expression in terms of x for the velocity of the oil in the pipe.
PROBLEM 3: A venturi meter with a throat diameter of 6 cm is fitted in a horizontal pipeline of 12 cm diameter with oil of specific gravity 0.88 flowing from left to the right. The difference in level in the two limbs of a mercury manometer connected to the tapping points read 12 cm and the connecting pipes are filled with the same oil.

Q1 Determine the minimum size of glass tubing that can be used to measure water level, if the capillary rise in the tube is not to exceed 0.3 mm. Take surface tension of water in contact with air as 0.0735 N/m. A U-tube is made up of two capillaries of bores 1.2 m and 2.4 mm respectively. Q2) The tube is held vertical and partially filled liquid of surface tension 0.06 N/m and zero contact angle.
