Q.23 Consider the flow of water through the frictionless pipe as shown in the figure. There is a sudden expansion at a section in the pipe. The flow velocity is 2.5 m/s and 1 m/s in AB and BC portion of the pipe respectively. The reading '' of the mercury- water differential manometer is: [Take specific gravity of mercury as 13.6] A O 50 cm Q B ↓ Water }
For Fig. Water flows through a pipe at rate of 350 L/S. The Pipe consists of two sections of diameters 300mm and 150 mm with a smooth reducing section that connects them.

Q-4 The apparatus shown in the figure is used to measure the velocity of air at the center of a duct having a 10 cm diameter. A tube mounted at the center of the duct has a 2 mm diameter and is attached to one leg of a slant-tube manometer. A pressure tap in the wall of the duct is connected to the other end of the slant-tube manometer. The well of 10 cm p = 150 kPa the slant-tube manometer is sufficiently large that the elevation of the fluid in it does not change significantly when fluid moves up the leg of T= 20°C the manometer. The air in the duct is at a temperature of 20°C, and the pressure is 150 kPa. The manometer liquid has a specific gravity 30 of 0.7, and the slope of the leg is 30°. When there is no flow in the duct, the liquid surface in the manometer lies at 2.3 cm on the slanted scale. When there is flow in the duct, the liquid moves up to 6.7 cm on the slanted scale. Find the velocity of the air in the duct. Assuming a uniform velocity profile in the duct, calculate the…
