Problem 1. An engine produces work due to the heat transfer from a thermal reservoir at temperature Tres and rejecting energy to a thermal sink at temperature Tsink. The efficiency of such cycle is &= 1- - (Tsink). Calculate the required uncertainty in the measurement of temperature to provide an Tres uncertainty in the cycle's efficiency of 3.5 %. Use Tres = 1250 K and Tsink = 300 K.
