A certain automobile model is offered with two engine options. The two engines are identical V8s with different displacements; one is and the other is the engines are run at identical speeds, temperatures, and operating conditions.
Calculate:
(a) Rough approximation of what percent greater (or less) will be the indicated thermal efficiency of the larger engine versus the smaller. [%]
(b) Approximation of what percent greater (or less) will be the total heat transfer to the coolant fluid of the larger engine versus the smaller. [%]
