WATER HAMMER 149. Problem The elasticity and dimensions of a pipe are such that the celerity of pressure wave is 975 m/s. The pipe diameter is 1.2 m. and a valve is located 600 m. dowstream. Water is flowing initially at 0.85 m/s. O Find the water hammer pressure for instantaneous valve closure. a) 467.68 KPa b) 371,25 KPa c) 231.87 KPa d) 145.98 KPa ® What is the approximate water-hammer pressure if the valve is closed in 4 sec? a) 232 KPa b) 225 KPa c) 246 KPa d) 251 KPa O What is the water-hammer pressure if the valve is manipulated so that the flow rate drops almost instanitly from 0.85 to 0.28 m/s. a) 132.91 KPa b) 274.5 KPa c) 487.5 KPa d) 367.4 KPa
