. A galvanized iron service pipe ( ϵ = 0.15 mm) is required to deliver a flow rate of 0.5 m3/s. If the length of the pipe is 200 m and the head loss is not to exceed 50 m, calculate the minimum pipe diameter that can be used by trial and error. Assume an initial value of 0.025 for f.

A 250 mm diameter of cast iron pipe flows 39.3 L/s of SAE 10 oil along 500 m length. Given: dynamic viscosity, μ and density, ρ of SAE 10 oil are 1.04 x 10-1 Ns/m2 and 917 kg/m3 respectively. By assuming the flow is laminar, determine energy head and pressure loss due to pipe friction using Hagen-Poiseuille equation and friction factor, f.

A pump is used to deliver water from a large reservoir to another large reservoir that is 20 m higher. The inlet of the pipe is submerged in the one reservoir and the exit is just above the surface of the other reservoir. If the friction head loss in the 200-mm-diameter, 4-km-long pipeline is 2.5 m for every 500 m of pipe length, determine the required power output of the pump so the flow is 0.6 m3/s.
