ECONOMIC DESIGN OF PIPE-NOZZLE DISCHARGE LINES DELIVERING FREE JETS

The present study focuses on finding an economic design of nozzles used in water discharge lines. An analytical solution is reached for computing the pipe-nozzle diameter ratio achieving minimum pipe cost using derivative method. derived equation shows that at a particular ratio, CP minimum. However, this evident from worked illustrative example. On comparison basis between and conventional one, satisfactory reduction cost, which may reach 56.7%. It great interest to recognize that, by increasing relative distance 400, 231 % associated with increase power jet 41.5 %, are verified. Also, achieves ranging 34 39.7 depending frictional effects approach pipe. reflects reliability lines delivering free jets. there many engineering applications in; filters, flotation tanks, sedimentation storage trickling other units wastewater systems.
