SOLVED: Air at an initial temperature of 45°C is to be transported through a 50 m long, well-insulated pipe. If the mean friction factor in the pipe can be assumed to be 0.025, find the minimum pipe diameter that can be used to carry the flow without choking occurring if the inlet air velocity is:a) 100 m/sb) 400 m/s

SOLVED:Water flows through two sections of the vertical pipe shown in Fig. P8.88. The bellows connection cannot support any force in the vertical direction. The 0.4 -ft-diameter pipe weighs 0.2 lb / ft, and the friction factor is assumed to be 0.02 . At what velocity will the force, F, required to hold the pipe be zero?
