Two pounds of carbon dioxide (co2) as an ideal gas executes a carnot power cycle while operating between thermal reservoirs at 500 and 100of. the pressures at the initial and final states of the isothermal expansion are 400 and 200 lbf/in2, respectively. the specific heat ratio is k = 1.24. determine the thermal efficiency, the work for the isothermal expansion, in btu, and the work for the adiabatic expansion, in btu.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
