Design and construction of the impact of jet apparatus for the fluid mechanics laboratory

The design and construction of the impact of the jet laboratory apparatus have been completed. The design analysis was carried out for the apparatus's significant components: the pipe, the cylinder, the flat plate, the curved cup, and the spring. The areas of the big elbow PVC and nozzle pipe are 0.0010752 and 0.0004908 m2, respectively. The area and volume of the transparent PVC cylinder are 0.5026 m2 and 0.4021 m3, respectively. The area and volume of the flat plate and the hemispherical cup are 0.000625 m2 and 0.134 m3, respectively. The maximum weight the spring can carry was determined to be 70.1 N, while the highest mass was 7.1 kg. The deflection of the spring was calculated to be 4.3 m. The jet impact efficiency was 92 %. The results from the flat plate experiment with the nozzle at 90° showed that the mass increased from 0.05 to 0.5 kg, with a corresponding increase in discharge from 0.3162 to 0.7257 m3/s. The results from the curve cup for the nozzle at 180 ° showed that the mass increased from 0.05 to 0.2 kg, with the same increase in discharge from 0.156 to 0.1891 m3/s, while the discharge decreased from 0.189 to 0.1766 m3/s, as the mass increased from 0.25 to 0.5 kg.
