A steel pipe is used to drain water from a reservoir that is 50 m above the datum, and water is discharged into the air at the elevation of the datum. The pipe is 1500 m long and 450 mm diameter and 50 mm wall thickness. A valve is installed at the downstream end of the pipe allows a flow rate of 0.71 m³/s. The valve was completely closed in 1.4 sec. Calculate maximum hammer pressure at the valve. The pipe is longitudinally anchored. Eb = 2.1×10° N/m², Ec=1.9×10¹¹ N/m².

The flowrate of the flow is 0.20 + a/10 m3 /s in a pipe placed on a horizontal plane. The pipe diameters are D1= 0.30 m and D2= 0.20. Please find the force acting to the pipe by the flow. The gauge pressure at (1) is p1 =200 + b*10 kN/m2 . (g=9,81 m/s2, g=10kN/m3 ) a= 4 b=3
