The pressure drop needed to force water through a horizontal 1-in.-diameter pipe is 0.40 psi for every 9-ft length of pipe. (a) Determine the shear stress on the pipe wall. Determine the shear stress at distances (b) 0.3 and (c) 0.5 in. away from the pipe wall.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
