Diesel cycle problem using variable specific heats

[@Innojr5]

Why did you say compression ratio was 1/20 for v2/v1 instead of 20?

[@antiquarian1773]

v2/v1 is the inverse of the compression ratio, the inverse of compression is expansion.

shouldn't Q(4-1) be 804? You do h4-h1 right? 1113.9-310.2 = 804 ish

[@eliseobalderas2145]

Can you explain how he got T4?

[@nicobrouwer4598]

Eliseo Balderas you can use T3 to find your vr3 and then using (v3/v4)=(vr3/vr4) you can find your vr4 which you can use get h4 and T4. The v3/v4 basically equals (rc/r). That’s how I did it at least

I see my error now, not stated all that well in the video.

very clear, thank you
