Water flows at a rate of 0.011 m³/s in a horizontal pipe whose diameter increases from 6 to 11 cm by an enlargement section. If the head loss across the enlargement section is 0.67 m and the kinetic energy correction factor at both the inlet and the outlet is 1.05, determine the pressure change. Take the density of water to be 1000 kg/m³. The pressure change is kPa.

Consider the pressurized horizontal pipe network consisting of three pipes arranged in series. The characteristics of each pipe are summarized in the table. The flow of water at Node A is Q = 5 cfs and the pressure head at Node A is yA = 200 feet. The temperature of the water is 60° F. a) Determine the friction head loss hfric in feet in Pipe 1. b) Determine the friction head loss hfric in feet in Pipe 2. c) Determine the friction head loss hfric in feet in Pipe 3. d) Determine the pressure head ys in feet at Node B. e) Determine the pressure head yc in feet at Node C. f) Determine the pressure head yo in feet at Node D.
