70. A siphon (an inverted U-tube) is used to steadily withdraw water from a large reservoir. The top of the siphon is 1.5 m higher than the surface of the water in the reservoir and the discharge side of the siphon is 8 m below the water surface. Ignore all frictional losses in the siphon. Find a) the mass flow rate of water dis- charged to the atmosphere and b) the pressure at the top of the siphon. Water is at T = 27 C and 1 atm. The diameter of the siphon tube is 5 cm. [Ans.: a) 24.6 kg/s and b) 7.86 kPa].

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
