Development of water - rocket thrust measurement stand / Sheikh Rizuan Jalaluddin

This project requires student to design and fabricate a water - rocket thrust measurement platform. The purpose of the platfonn is to measure the thrust produced by water jet. Which determine the optimum pressure required to produce maximum thrust. Parameter that influences the thrust are pressure and water volume. However this project can be made as a teaching aid and a potential research tool. The governing laws involved are Sir Isaac Newton's third law of motion which states for every action there will always be equal but opposite reaction and the principal of conservation of mass which relates refer Appendix D. This research methodology will explain the details of water- rocket thrust measurement platform. Empirical data collection is based on the water pressure relative to nozzle size and thrust produced. However comparisons mode on the experiment with the theoretical data shows some similarity of result values. The thrust measurement stand platform can be suitable for future research development and a teaching aid. It is found that the thrust produced is the product of the water expulsion mass flow rate with the velocity of the water jet out from the
bottle through the nozzle which concludes this research finding.
