(b) Due to a gear drove water pump
(c) Due to change in the density of water
(d) Due to a belt-driven water impeller
The question was posed to me in exam.
I'd like to ask this question from Heat Rejection and Cooling topic in section Nonconventional Engines, Conventional Energy Sources & Cooling System of Automobile Engineering
