The mechanical properties of aluminum may be improved by incorporating fine particles of aluminum oxide (al2o3). given that the moduli of elasticity of these materials are, respectively, 69 gpa (10 × 106 psi) and 393 gpa (57 × 106 psi), plot modulus of elasticity versus the volume percent of al2o3 in al from 0 to 100 vol%, using both upper- and lower-bound expressions.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
