The actual discharge from nozzles will vary from 90% to 95% of the theoretical discharge. For hydraulic sluicing the following pressures at base of nozzles are recommended:
Light fine material and loose sandy soil:
Stiff loam overburden:
Hard clay:
The following amounts of water are recommended to move 1 cubic foot:
Heavy sand:
Average quarry overburden:
(3.D.1) $$ Q = 19.636*C*{d_1}^2*\sqrt {h} $$

For sprinkling golf courses it is reasonably safe to figure 10 gallons per minute for each Green with 35 PSIA at hose valve outlet and 25 gallons per minute for each Fairway with 35 PSIA at hose valve outlet. The standard conditions are 100 feet of ¾ inch hose for greens sprinklers and 100 feet of 1 inch hose for fairway sprinklers. Use gate valves with a hose nipple at all outlets instead of the customary hose faucets on account of the friction loss in the hose faucets.
Hydraulic Modeling and Simulation of Pumping Systems - 2 Part Webinar
This course discusses the differences between component optimization and system optimization and demonstrates how analysis software can be used to improve pump system operation. It provides examples and case studies demonstrating how hydraulic modeling software, such as the P·SMART tool, is used to diagnose and correct problems with pump system operation in real-world situations.
