1) A water fountain is to be installed at a remote location by attaching a cast iron pipe directly to a water main through which water is flowing. The entrance to the pipe is sharp-edged 15m (K-0.5), and the 15m long piping system involves three 90 bends without vanes (K1.1), a fully open gate valve (K.-0.2), and a fully open angle valve (K-5). If the diameter of the pipe is 2 em and the system is to...
Problem 3: The following data were obtained for flow of 20°C water at 20 m/hr through a badly corroded 5-cm-diameter pipe which slopes downward at an angle of 8°: pı -420 kPa, zi -12 m, p2- 250 kPa,...
Problem 3: The following data were obtained for flow of 20°C water at 20 m/hr through a badly corroded 5-cm-diameter pipe which slopes downward at an angle of 8°: pı -420 kPa, zi -12 m, p2- 250 kPa, z2- 3 m. Estimate (a) the roughness ratio of the pipe; and (b) the percent change in head loss if the pipe were smooth and the flow rate the same. For water at 20°C, take ρ-998 kg/m3 and μ-0.001 kg/m s

5.16. Water is flowing in a 3-cm-diameter pipe at an average velocity of Uav 2 m/s. Assuming water density of ρ-1000 kg/m 3 and viscosity μ-10-3 N s'm2, calculate the velocity at the center of the pipe, the shear τ at the wall, and the Reynolds number. Assuming laminar flow, calculate friction coefficient C and pressure drop dp/dx.

Water is flowing through a 10-cm-diameter water pipe at a rate of 0.1 m/s. Then, a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water as it exits the diffuser to atmospheric pressure, as shown in the given figure. Disregarding frictional effects, determine the force exerted on the bolts due to the water flow. Take the density of water to be 1000 kg/m3 -t- d 10 cmm D = 20...
