🔍 Key Concepts

• heat transfer surface area vs. gas temperature • effect of mass flow rate of hot gases over boiler tubes • role of gas turbulence in heat transfer

💭 Think About

• Which change will actually transfer more total heat per unit time to the water/steam inside the boiler tubes? • Does simply having a higher peak temperature matter more, or does moving more hot gas across the heating surfaces matter more? • How would increased or decreased gas turbulence affect how well heat is transferred from the gas to the metal surfaces?

✅ Before You Answer

• Identify which option clearly relates to an increase in overall heat transfer rate to the water, not just local temperature rise • Check which choice correctly describes the effect of combustion rate on how much hot gas passes over the boiler tubes • Eliminate any choice that would likely reduce heat transfer effectiveness, even if temperature seems higher
