Air flows in an 10-cm-diameter, 50-m-long pipe at a velocity of 2.75 m/s. The piping system involves multiple flow restrictions with a total minor loss coefficient of 3.5. The friction factor of pipe is obtained from the Moody chart to be 0.03. The total head loss of this piping system is

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
