Argon enters a pipe at 100 kPa and 27oC and is compressed (via a compressor. meaning work is being done on the system) in an adiabatic, steady flow process to 200 kPa abd 100oC at the exit. Calculate the work required for this process in KJ/kg.
Design a wide flange, simply supported beam below so that the stress due to bending does not exceed that allowed by AISC for A36 steel and calculate the shear stress where the parts join as indicated. Maximum V = 10,000 lb.
Niobium forms a substitutional solid solution with vanadium. Compute the weight percent of niobium that must be added to vanadium to yield an alloy that contains 1.55 x 1022 Nb atoms per cubic centimeter. The densities of pure Nb and V are 8.57 an..
