Sulphuric acid is flowing through a pipe (2.5 inch diameter, 50 ft length) in a velocity of 0.006 m3 /s. The sulphuric acid has a viscosity of 25 mN.s/m2 and density of 1680 kg/m3 while the roughness of the pipe surface is 1.3 mm.

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...
