Abstract
ABSTRACT: Water is central to survival, without water human, plant and animal life would be impossible. Therefore supply of water has become one of the fundamental requirements of any society and the need to transfer water has generated the design of various forms of mechanical devices, which can be categorized as pumps. Jet pump is a device that performs its pumping action by the transfer of energy from a high velocity supply jet to one of low velocity suction flow. These two flows mix in the mixing tube and the kinetic energy of the combined flow is converted partially into the pressure energy in the diffuser. The optimization of the design of multi hole nozzle jet pump with various pitch circle diameter (PCD) and five different diameter mixing tubes. The area ratios chosen have been modified and the final area ratios used were R = 0.20, 0.28, 0.36, 0.43 & 0.50. From the graphs, head ratio at zero discharge ratios (No), discharge ratio at zero head ratio (Mo) and slope of M-N (m) curve were noted along with the extrapolated values of maximum efficiency (bep), optimum discharge ratio (Mopt), and optimum head ratio (Nopt) and tabulated. In order to distinguish these nozzle plates from these charts one can conclude that efficiency is higher at lower pitch circle diameter, lower mixing tube diameter and higher area ratios. In the range of experiments conducted highest maximum efficiency was obtained for an area ratio of 0.43 with 2 holes on 13 PCD with 25.9 mm mixing tube.
