The Figure below (Figure 3) shows a horizontal rectangular air duct of width B = 1 m and height H = 0.3 m which carries air at a flow rate of Q = 2.5 m³/s. The duct is made of commercial steel. The horizontal duct system has no change in elevation between cross-sections (1) and (2). Hint: In non-circular conduits, the diameter D of circular pipes, is replaced by the hydraulic diameter DH = 4 x RH in all relevant equations.

As shown in the figure, the water flows from the ground floor of a three-storey house to the second floor through pipes of 20 mm diameter (average roughness of the pipe material = 0.0015 mm) at a volumetric flow rate of 0.75 L / s. Water is discharged from the system to atmospheric pressure through a tap with a 12 mm diameter outlet. There are 4 winged elbows, one ball valve and one faucet throughout the installation. Calculate the effective pressure at point 1. (psu=998 kg/m3, usu=1.12x10-3 Pa s, g=9.81 m/s2)
