Chilled water velocity in pipe as per ashrae
Web4.0 A high chilled water temperature rise in the coil is required to reduce pumping horsepower and to increase the efficiency of refrigeration equipment. A minimum 15°F rise is recommended, and in some cases a rise as high as 17°F can be economically achieved. 5.0 The chilled water coil face velocity should not be more than 400 FPM on new ... WebMar 3, 2016 · One recommendation places a velocity limit of 1.2 m/s for 50 mm pipe and smaller, and a pressure drop limit of 400 Pa/m for piping over 50 mm. Other guidelines are based on the type of service (Table 8) or the annual operating hours (Table 9).

WebSep 10, 2002 · I will first answer regarding the minimum flow velocity in a pipe.The minimum velocity is generally dictated by economic considerations; if you take a lesser velocity you end up with a bigger pipe size.The other considerations would be fouling characteristics of the fluid. WebIn a variable primary chilled-water system, the design flow rate is determined by the water flow velocity in the tube of the coils. At typical conditions, 6–7 feet per second (1.8–2.1 m/s) Maximum 12 ft/s (3.7 m/s) Minimum 1.5 ft/s (0.46 m/s) (based on a Reynolds number of 7500) Minimum flow is typically 50% or less of the design flow.
