STUDY OF IMPACT OF JET ON DIFFERENT VANES FOR MEASURING FLOW RATE AND IMPACT FORCE

Abstract

The objectives of the thesis paper are to conduct an investigation into the reaction force generated by the impact of a jet of water onto various target vanes and to compare between experimental and theoretical forces which are exerted by the jet. The procedure for this experiment is to bring the weight cup in the initial position by applying weight when the flow rate is varied. The same experiment can be repeated by changing different target vanes. Moreover, the effect of different target vanes can be seen at constant flow rate by changing the type of target vanes and applying different amounts of weights to bring the weight cup in the initial position. The vanes used in this experiment can be categorized into four geometries. Flat, inclined, spherical and conical vanes are used for this experiment. Experimental and theoretical forces and the percentage of error can be calculated in this experiment. Here, the theoretical forces are depended upon weights applied on the weight cup and the experimental forces are depended on flow rate, nozzle exit velocity, impact velocity and shape of the vanes.
