P1.8 Create a model of the impeller shown in Figure P1.8A. An impeller is used in a pump to increase the speed of a fluid. As the impeller rotates, fluid entering

through the hole in the front plate is propelled outward. Begin by creating the back plate, hub, and center hole (for mounting onto a shaft), as shown in Figure PI.8B (all dimensions are mm). FIGURE PI.8A FIGURE P1.8B -Ø20 30- 150 050-
