Question in the picture
smooth pipe: Total length, L Diameter, d -25 mm 4 m tank water (pa 1,000 kg/m3, μ 0.001 kg/ms) flows from a very large tank (that is open to atmosphere) through an L 4 m total length of smooth pipe of d = 25 mm diameter at a bulk velocity of 6 m/s. The water then exits the pipe at 3 m above ground as a free jet. The pipe network contains a gate valve (V),...

A centrifugal pump test yields the following data: Pump Head Flow (m)(L/min) 30 25 20 40 The pump curve can be approximated by a parabola. This pump draws water from a large reservoir. The discharge of the pump feeds 150 m of 1.5 cm inside diameter pipe and then 225 m of 3 cm inside diameter pipe.. The two pipes both have a roughness of 0.5 mm The 3 cm pipe discharges to atmosphere a distance 40 m below the...
