23. Hr @A cast iron 18“ diameter pipeline carries 1water at TIFF over a distance of l,llllll It. If the flow velocityr is 5 His, the pressure is 46 psi and the pipe thickness is 11.5 inch, determine the following: a} The wave celerity in this pipe. h} The added pressure generated by a sudden closure. c} Would the sudden closure cause cavitation? d) How long 1would the closure time have to he to reduce the maximum pressure? c} What is the increased pressure it" the time ot'elosure 'u l s? [Answer N = 1.45 and op = 98 psi] t] A Ill ft diameter surge tank is built half-wagI between the power house and the reservoir. Whatis the maximum surge height? [Answer 3 = 3 it] g} What is the period of oscillations in the surge tank? [Answer T = 165 s]
