Consider an ideal turbine. the working fluid is air and the compressor is expanding flow from a state of 10 atm and 1700 k. on a single plot, graph the specific work produced by the air with (i) the specific heat ratio = 1.4 and (ii) the specific heat ratio fixed at 1.3 for a turbine exit pressure range of 10–1 atm.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
