Air flows through a device such that the stagnation pressure is 0.4 mpa, the stagnation temperature is 400°c, and the velocity is 528 m/s. determine the static pressure and temperature of the air at this state. the properties of air at an anticipated average temperature of 600 k are cp = 1.051 kj/kg·k and k = 1.376.

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
