The mean velocity of water in a 150 mm horizontal pipe is 0.9 m/s. Calculate the loss of head through an abrupt contraction to 50 mm diameter. If the pressure in the 150 mm pipe is 345 kPa, what is the pressure in the 50 mm pipe, neglecting pipe friction?

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.

A discharge of 2.8m^3/s flows through a hydraulic turbine. On the 1 m inlet pipe at elevation 43.5 m, a pressure gage reads 345 kPa. On the 1.5 m discharge pipe at elevation 39, a vacuum gage reads 150 mm of mercury. If the total head lost through pipes and turbines between elevation 43.5 and 39 is 9 m, what power may be expected from the machine?
