WebThe water velocity in a copper tube should be kept within certain limits to avoid erosion, corrosion and excessive noise generation. in cold water systems - the velocities should not exceed 8 feet per second (2.4 m/s) in hot water systems with temperatures below 140 oF (60 oC) - the velocities should not exceed 5 feet per second (1.5 m/s) WebIn addition to the formula, ASHRAE also split the calculation for threaded and flange valves and pipe fittings. However, ASHRAE didn’t discuss the required water velocity in the same section but I’ve included it in my excel calculator. 5. Flange Pressure Rating Calculator Excel I’ve had a blog post about closed loop chilled water system pressure. WebJan 22, 2024 · As per attached ASHRAE reference the recommended lowest chilled water pipe velocity to be maintained in chilled water pipes is 0.6 m/s. In my current fit-out project I have to use existing chilled water pipes for new fit-out flow rates where the pipe velocities are dropping below 0.6 m/s. chilmington green primary
