Để nhiệt độ của một lượng khí tăng thêm một lượng denta T, thì nên truyền nhiệt cho nó bằng cách đẳng áp hay đẳng tích? Vì sao?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

Carbon 14 is a naturally occurring stable
