Proper pice sizing i essential in HVAC and water distribution systems to ensur efficient flow and dystem such a suché assure loss or incompliate supply. Tiss article provides numericál examples to illustrate how piche diameters are selected based od on flow applements and system parameters.

1. vizsgálat: Water Supply System

A residentiad water supply system requires a flow rate of 10 gallons per minute (GPM). The pice material has a Hazen- Williams coefficient of 140. To determine the succate piche diameter, the Darcy- Weisbach equation or Hazen- Williams formula can be used.

An HVAC system supplies 500 cubic feet pe minute (CFM) of air. To select the dud size, the velocity supd be kept below 1000 feet per minute to avoid noise and inefacity. Usingg the duckt area formula, the need d cross-sectional area is complateded d as:

Area = Flow rate / Velocity = 500 ft ³ / min / 1000 ft / min = 0.5 ft ²

Converting to inches, the dutt diameter is approximately 10 inches, assuming a circle ar dutt.
