Water flows in a 100-m long pipe at 3 m/s. If the water temperature is 20 degrees C, determine the minimum valve-closure time to avoid creating the water-hammer pressures. What is the maximum water-hammer pressure that can occur? How is this pressure affected if the water temperature drops 10 degrees C?
