24. In Fig. 5, the operating point is a) (A) B(B) c) (C) d) (D) 25. A clothes dryer device with 40C air flows. The 10cm diameter galvanized iron vent on the clothes dryer is not to contain more than 6m of pipe and four elbows ( 90 regular threaded). The air inlet pressure Pl is 0.5cm of water. Determine PJ. a) Pl=29.05Pa b) Pl=39.05Pa Pf=49.05Pa d) PI=59.05Pa 26. For the same quistion (25), the Bernoulli equation can be derived as follows: p1/=fl/D+Kl b) 2gp1/V2=fl/D+K1 c) (p1/)(V2/2g)=Kl d) (p1/)(V2/2g)=fl/DKl 27. For the same quistion (25), the Bernoulli equation is 87=(6.0+60f)V2,Re=6020V, and /D=0.0015. The first guiss of the friction factor is f=0.02. Determine the calculated Reynolds number for this first guiss. a) 19926 D) 20926 c) 21926 d) 22926
