The frictional mechanical work is calculated as a function of the rotational direction of the calorimeter in the Puluj-type experimental setup (a calorimeter with water inside). Based on this calculus, a new experimental strategy is proposed for demonstrating the equivalence of heat and mechanical work, which reduces the number of physical quantities that need to be measured during the experiment.
