Air entering the compressor section of a jet engine is at a temperature of 15°c and a pressure of 1 atm.
the compressor features a pressure ratio of 7.

assuming :

(a) air is an ideal gas

(b) constant specific heats at room temperature

(c) the compressor is isentropic,

what is the temperature of the air at the exit of the compressor (°c)?

Consider a spherical container of inner radius , outer radius r2, and thermal conductivity k. express the boundary condition on the inner surface of the container for steady one-dimensional conduction for the following cases: (a) specified temperature of 50°c, (b) specified heat flux of 30 w/m2 toward the center, (c) convection to a medium at t with a heat transfer coefficient of h
