The hot reservoir for a Carnot engine has a temperature of 943 K, while the cold reservoir has a temperature of 495 K. The heat input for this engine is 5280 J. The 495-K reservoir also serves as the hot reservoir for a second Carnot engine. This second engine uses the rejected heat of the first engine as input and extracts additional work from it. The rejected heat from the second engine goes into a reservoir that has a temperature of 191 K. Find the total work delivered by the two engines.
