A pipe is 39 m long and 150 mm in diameter and has water flowing through it at a rate of 0.175 m3 /s. The pipe has its inlet 12 m below its outlet and somewhere along the pipe is a valve with a loss of 0.4(c2/2g ) (40 % loss of velocity head) . If the friction loss per meter run of pipe amounts to 0.149 m, determine the change in static pressure (kPa) between the inlet and the outlet, neglect the length of the valve.
