ABSTRACT

P1 = (ρcQ/Th)( T)2 (14.4) Example 14.1 Required flow rate For T = 20°C the flow rate required to yield 1 MW from an ideal heat engine is (from (14.4))

(ss 650th"1)

Thus a substantial flow is required to give a reasonable output, even at the highest T available in the world. This requires large, and therefore expensive, machinery.
