The discussion centers on calculating the velocity and power of water streams exiting orifices under high pressure, specifically at 60 ksi through a 0.015" orifice. Participants request more detailed information and diagrams to provide accurate answers for two scenarios involving solenoid valves and the effects on stream velocity. The importance of smooth, laminar flow is emphasized, and the absence of a system relief is noted for simplification. A reference to a research paper indicates that a 1 mm orifice at 420 MPa achieves a velocity of 916 m/s, verified through advanced measurement techniques. The conversation also touches on the energy dispersion rate from the nozzle tip to the atmosphere and the potential impact of the water stream on human bodies.
