Water flows at a rate of 0.035 m3 /s in a horizontal pipe whose diameter is reduced from 15 cm to 8 cm by a reducer. if the pressure at the centerline is measured to be 480 kpa and 445 kpa before and after the reducer, respectively, determine the irreversible head loss in the reducer. take the kinetic energy correction factors to be 1.05.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
