**1.Recently, we performed an experiment to measure the efficiency of the Stirling Engine. The experimental method can be seen in the image provided. We have been asked to calculate the power dissipation P**

At R = 500Ω, the recorded values are:

^{R}and the energy dissipation per cycle W_{R}as part of our lab report. The other variables mentioned are R (the resistance), U_{R}(the measured voltage), n (the revolutions per min), T_{1}and T_{2}, the temperature of two thermocouples connected to the engine.At R = 500Ω, the recorded values are:

**U**_{R}= -3.68V, n = 494 cycles min^{-1}, T_{1}= 150°C and T_{2}= 63.2°C.**2.**

**P**_{R}= V^{2}/R**W = P*t (where W is work, P is power and t is time)**

**3. I was able to calculate the Power Dissipation using the above equation (P**

_{R}= 0.027 W) but I'm totally lost on finding W_{R}. I've tried using the above equation and subbing in**W**_{R}and**P
**_{R}and finding the time it takes for 1 cycle but that gives me a very small number when compared to the value of W_{pV}= -2.4498J.
