say i have a 1.5m diameter and 7m lond pipe, blocked of at one end and leading into a 2.8m diameter horizontaly laid manifold (so that effectively you have one small pipe branching of another large pipe), the pipes are filled with water. In order to calculate the resonance frequencies, i would assume the large pipe is effectievly an open end.
How much would that assumption effect the values of the resonant frequencies calculate?
Also, if the water was flowing through the closed end of the small pipe(through a insignificatly small hole in the valve) at say no more than 4m/s, would this velocity effect the frequencies?
