Several Goulds 1x 3-8 pumps are available for use with 1,750-rpim motors. The system characteristics are given by H = 0.002Q° for the parallel system and H= 0.020Q for the se- ries system, where Q is in gpm and H is in ft-lbf/bm. (a) If two pumps with 8-in. rotors are placed in series, find the equivalent pump curve, the sys- tem operating point, the pumps' operating points, and the power required by each pump. (b) Work part (a) if one 8-in. rotor pump and one 73-in. rotor pump in series are used. (c) Work part (a) if two 8-in. rotor pumps are in parallel. (d) Work part (a) if one 8-in. rotor pump and one 73-in. rotor pump are in parailel. (e) Work part (a) if one 8-in. rotor pump, one 73-in. rotor pump, and one 7-in. pump are in parallel. The pump characteristics are given in Problem 2. MODE 196 ST SZE/2x3- IMP.
