Transcribed Image Text:
You have been asked to analyze the effect of an instantaneous valve closure at the end of a 3.0 km pipeline, transferring water to a local suburb. Water is typically pumped at a velocity of 0.5m/s and the internal diameter of the pipe is 150mm. The bulk modulus of water is 2068 MPa. If the velocity of the compression wave is 1455m/s, determine the initial increase in pressure in the pipeline, as a result of an instantaneous closure of the valve. Overview R Closing the valve brings the fluid behind it to rest (v=0), this fluid is compressed as it brings the fluid behind it to rest. This process continues along the length of the pipe. The density of the fluid at rest is higher than the fluid moving with velocity (V). What happens next depends on the conditions at the entrance to the pipe and we do not know what they are for this problem.
