A 600mm diameter pipeline carries water under a head of 30m with a velocity of
3m/s. This water main is fitted with a horizontal bend which turns the axis of the
pipeline through 75° (i.e. the internal angle at the bend is 105°). Calculate the
resultant force on the bend and its angle to the horizontal.

A 100-m long horizontal pipe carries water at an average velocity of 2.5 m/s. The required pressure drop, deltaP, across the length of the pipe required to achieve this is 1.5 x 10^5Pa, and the surface roughness to diameter ratio of the inside of the pipe is k/D= 0.004. What is the diameter of the pipe? The only current example on chegg of this problem is wrong.

Water (ρ = 999 kg/m3, μ = 1.3x10-3 N/s) from a large tank with P1 flows through a pipeline at the rate of 0.14 m3/s to atmosphere as shown. The pipe diameter of the entire piping system is 20 cm and material is cast iron. Knowing discharge velocity V2 is the same as the flow velocity in the pipe, no discharging nozzle loss, Kinlet = 0.5, and Kelbow = 1.1, calculate the absolute P1 (MPa) in the tank needed to...
