As the air goes through the compressor of a gas turbine engine, it undergoes an increase in pressure such that the pressure ratio at the compressor exit to the compressor inlet is 15 (Note this is a ratio and not a difference). What is the ratio of exit to inlet density, given the bulk modulus of air is 101000 N/m2

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

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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.
