A typical air-duct system is shown Figure 2.68 below: Figure 2.68: An air conditioning duct system Determine: (a) the duct sizes using the Equal Pressure Drop Method. The air velocity in the first section is not to exceed
8(m)/(s). Also, estimate the static pressure in the index run of the duct network. Assume a pressure drop of 7 Pa at each of the outlet grilles; (b) equivalent rectangular duct system.
