Webb22 juni 2012 · As a rule of thumb the velocity should be kept below: V = 175 X (1/ρ)^0.43 Where, V is the maximum velocity of gas to avoid noise in m/s and ρ is the density of gas in kg/m3. When dP is not critical: Velocity is 60 m/s (or the lowest value) When dP is critical: dP is set depending on the operating pressure. Webb4. Determine the Chilled Water Pipe Size. Pull the horizontal line for the flow at 4.8 gpm (blue line) and find the pipe size within the design criteria. For this example, I get a 3/4″ pipe size (pink line). I check both the friction loss and …
