For steam system to work properly, it is important to maintain reasonable velocities of liquid passing through piping. Velocity is constant for a given flow rate and independent of pipe length. Pipe diameters are selected to achieve a velocity of 5-10 feet per second. Chart versions o...
NPSH and its effect on pump-sizing are reviewed in Chapter 5. From Table 4-12, select 6 ft/s as design velocity for estimating pipe size. For 20 gpm, cross-section area for flow required. A=20gpm7.48gal./ft3(60s/min)(6ft/s)=0.007427ft2=(0.007427)(144)=1.0695in.2 Pipe diameter ...

pipe wall smoothness and internal pipe surface area. Pipe and fitting manufacturers, using the Hazen-Williams formula, have calculated and have readily available the friction loss and velocity data for all their products. Valve manufacturers have calculated liquid sizing constants (Cv values) for each...
