Question 143Motor Plants - QMED70% to pass
The highest pressure in any closed diesel engine fresh water cooling system is at the _______________.
AI Explanation
The correct answer is C) cooling water pump outlet.
The highest pressure in any closed diesel engine fresh water cooling system is at the cooling water pump outlet. This is because the cooling water pump is responsible for circulating the coolant through the engine block, heat exchanger, and the rest of the cooling system. The pump generates the necessary pressure to push the coolant through the system, and the pressure is highest at the pump's discharge.
The other answer choices are incorrect because the pressure is lower at those locations in the cooling system. The jacket water outlet, expansion tank inlet, and heat exchanger inlet are all downstream of the cooling water pump, where the pressure has been reduced by the flow resistance of the piping and components.
