An аir cоmpressоr prоvides 6700 kW to rаise аir from an inlet temperature T_1 = 300 K and inlet pressure p_1 = 1 bar to an outlet pressure T_2 = 620 K and outlet pressure p_2 = 12 bar. (a) What is the mass flow rate of air through the compressor, in kg/s? _______ kg/s. The air leaving the compressor flows through a regenerator, where it exchanges heat with a second air stream. The stream leaving the compressor leaves the regenerator at T_3 = 760 K and p_3 = 12 bar. The second air stream enters the regenerator at T_4 = 780 K and p_4 = 1 bar. Its mass flow rate, m_dot_4, is double the mass flow rate of the stream flowing through the compressor. (b) Find the temperature, T_5. Use linear interpolation to obtain an answer that is accurate to 0.1 K. _______ K.
