A sharp edged weir is to be constructed across a stream in which the normal flow is 200 litres/sec. If the maximum flow likely to occur in the stream is 5 times the normal flow then determine the length of weir necessary to limit the rise in water level to 40cm above that for normal flow. Cd=0.61.

The right limb of a simple U-tube manometer containing mercury is open to the atmosphere while the left limb is connected to a pipe in which a fluid of sp. gr. 0.9 is flowing. The centre of the pipe is 12 cm below the level of mercury in the right limb. Find the pressure of fluid in the pipe if the difference of mercury level in the two limbs is 20 cm.

A Newtonian fluid is filled in the clearance between a shaft and a concentric sleeve. The sleeve attains a speed of 50 cm/s when a force of 40 N is applied to the sleeve parallel to the shaft. Determine the speed if a force of 200 N is applied. Leave a Comment / Fluid Mechanics, Numerical (Water) / By Ashok Sapkota / July 28, 2025
The figure below shows a pipe connecting a reservoir to a turbine which discharges water to the tailrace through another pipe. The head loss between the reservoir and the turbine is 8 times kinetic head in the pipe and that from the turbine to tailrace is 0.4 times the kinetic head in the pipe. The rate of flow is 1.36m3/s and the pipe diameter in both cases is 1m. Determine (a) the pressure at inlet and exit of turbine, and (b) the power generated by the turbine.
