Water flows through a new cast iron pipe at a velocity of 1.8 m/s. The pipe is 480 m long and has a diameter of 150 mm. Determine the head loss due to friction using Manning's formula with n = 0.012.

Bernoulli's theorem demonstration: 5 L of Water is flowing through a venturimeter in 6.5s. What is the pressure difference (p1- P2) (in kPa) for this flow? D=32 mm, d=23 mm, g = 9.8 m/s² and y=9.8 kN/m³

Determine the magnitude and location of the total hydrostatic force acting on the 2m x 4m gate shown in the figure. Ans. F= 733.16kN, 1.844m from the bottom of the tank parallel to the gate

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
