Using velocity reduction method, design the duct system. Take the velocity of air in main duct as 8m/sec, air density 1.2kg/m. Coranch = 0.4 Coutlet = 1 2. Using equal pressure drop method, design the duct system. Take Ap = 1pa/m, air density 1.2kg \m. Cranch = 0.4 Coutlet = 1
Find the loss in total pressure for each run in the simple duct system of Fig. 1, using the
equal-friction method and in English unit. The total pressure available for the duct system
is 0.12 in. wg (30 Pa), and the loss in total pressure for each diffuser at the specified flow
rate is 0.02 in. wg (5 Pa). Duct fittings are listed in Table 1. Assume the duct dimeter in
run 1 is 10 in. and the rest are 8 in. Does the duct system require any adjustment?

A Forced - Draft (FDF) with open suction has rated capacity of 4,000 CFM at 1,800 rpm. The pressure developed at the discharged duct is 10 mm H2O. The discharge duct is circular with inside diameter of 600 mm. Calculate the following:a) what is the velocity of air at the discharge in mm H2O?b) what is the theoretical fan power required in kW?Consider standard density of water and air are 1000 kg/m3 and 1.20 kg/m

The effective length-including fittings-of the commercial steel pipe is 6,000 ft. The discharge at point 4 is 200 ft above the pump exit, which is level with the free surface of oil in the tanker. However, because of an intervening hill, point 3 is at a higher altitude than point 4. Losses between points 1 and 2 may be ignored. The crude oil has the following properties: Density p = 53 lbm/ft3; Viscosity u = 13.2 cP; Vapour Pressure Pv = 4.0 psia 1,000 ft 5,000 ft Storage tank 200 ft Oil tankerarrow_forward
