The intermediate pressure bleed steam system, shown in the illustration, is used to supply steam at approximately _______________. Illustration SG-0024
AI Explanation
The correct answer is D) 67.0 psig.
The intermediate pressure bleed steam system is used to supply steam at approximately 67.0 psig. This is based on the typical operating pressure range for this type of steam system on commercial vessels. The intermediate pressure bleed steam is taken from the main steam system at a point where the pressure is around 67 psig, which is lower than the main steam pressure but higher than the low-pressure steam used for other purposes.
The other answer choices are incorrect because 13.6 psia is an absolute pressure measurement, not a gauge pressure, and 13.6 psig and 35.0 psig are not the typical pressures for an intermediate pressure bleed steam system on a commercial vessel.
