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 "spa tub" is to be designed to replace bath tubs in reno-
vations. There are to be 6 outlet nozzles, each with a di-
ameter of 12 mm, and each should have an outlet velocity
of 12 m/s. What is the required flow rate from the single
pump that supplies all of these nozzles? If there is one
suction line leading to the pump, what is the minimum
diameter to limit the velocity at the inlet of the pump to
2.5 m/s?

A duct of 0.45 m diameter and 90 m long leads from a fan discharge chamber where the pressure is 15 mm of water to a plenum chamber where the pressure is 10 mm of water. In order to increase the flow, two alternatives are considered. One is to lay a duct of 0.3 m diameter and 90 m long in parallel with the duct of 0.45 m diameter. The other is to increase the diameter of 0.45 m diameter duct for the last 60 m length. Calculate the increased diameter so that this method gives the same flow as the 0.45 m and 0.3 m ducts in parallel. Assume that the pressures in the fan chamber and plenum chamber are unaffected by changes in the flow and consider duct friction losses only. The friction factor may be taken as 0.0o55. 6. A 0.3 m diameter circular duct carries standard air at a velocity of 360 m/min. It is replaced by a rectangular duct having the same pressure loss per unit length due to friction.

A conical tube is fixed vertically with its smaller end upwards and it forms a part of the pipeline. The velocity at the smaller end is 4.9 m/s and at the larger end is 2.5 m/s. The length of the conical tube is 1.3 m and the flow rate of the water is 127 liters/s. The pressure at the smaller end is equivalent to a head of 10.1 m of water. Considering the following two cases: (1) Neglecting friction, (without head loss) determine (i) the diameter at the smaller end in meter, (ii) the diameter at the larger end in meter, and (ii) the pressure at the larger end of the tube in m of water. (2) If a head loss (with head loss)in the tube,h = 0.0153(V1-V2)2, where V1 is the velocity at the smaller end and V2 is the velocity at the larger end, determine (iv) the head loss in m of water and (v) the pressure at the larger end of the tube in m of water. 6) the diameter at the smaller end in meter (ii) the diameter at the larger end in meter (iii) the pressure head at the larger end of the…arrow_forwardb) Calculate the power consumption and the steady discharge of water between the reservoirs in the pipeline system shown in Figure 4.1.

A centrifugal pump is to be placed above a large, open water tank, as shown in the figure below. Water is pumped at a rate of I cu ft/s.
