Explain about the control and isolation joints and their purpose and usual position in a concrete slab.

Question

Water (at 10° C has n = 1.31 x 106 m²/s) flows from reservoir A (surface elevation 100 m) through a 2.25-m-diameter concrete pipe (e = 0.36 mm; f=0.014) to reservoir B (surface elevation 91.84 m). If the 2 reservoirs are 17 km apart, find the flow velocity V (to 2 decimal places x.xx) ignoring minor losses. 100 m A L = 17 km P₁ h₁ + = + V² 2g D=2.25 m 91.84 m B + h₂ 2g P₂ = =h₂+ + V
