While underway on a steamship, the main condenser is operating under a 28.09 "Hg vacuum gauge. According to the illustrated properties of saturated steam table, how much condensate depression would there be if the condensate temperature leaving the main condenser hot well is 96.0°F?

🔍 Key Concepts

• Use the Properties of Saturated Steam table at the given vacuum of 28.09 inches of Hg gage to find the corresponding saturation temperature in °F. • Understand that condensate depression is the difference between the saturation temperature for the existing vacuum and the actual condensate temperature leaving the hot well. • Carefully subtract temperatures and compare the result with the multiple‑choice answers, watching for round‑off and sign (no negative depression).

💭 Think About

• What is the saturation temperature in °F that corresponds to a vacuum of 28.09" Hg on the table in the illustration? • Once you have that saturation temperature, how do you mathematically express condensate depression using the condensate outlet temperature of 96.0°F? • After calculating the temperature difference, which option most closely matches your computed value?

✅ Before You Answer

• Confirm you are reading the correct row: 28.09 inches of Hg gage in the table, and using the Temperature °F column, not °C. • Verify your subtraction order: saturation temperature − condensate temperature (so the result is positive for depression). • After you compute the value, check which choice matches your calculated difference to the nearest hundredth of a degree.
