🔍 Key Concepts

• Total system head loss in a closed cooling system • How individual pressure drops (engine + heat exchanger) combine • Difference between pressure (psig) and head in feet of water

💭 Think About

• How does the pump discharge pressure need to relate to the sum of all pressure drops in the circuit at maximum flow? • If one component drops 10 psig and another drops 4 psig, what is the minimum pressure the pump must overcome to push water through both in series? • Once you find the total required pressure in psig, compare it directly with the answer choices—do you need any extra conversion for this question?

✅ Before You Answer

• Add the pressure drops of components in series correctly • Confirm you are using psig consistently (not mixing with feet of head unless you convert) • Verify that you are not subtracting or averaging the pressure drops—look at total required pump head at max flow
