70% to pass

The required number of pounds of steam generated per hour to develop contract shaft horsepower and maintain the specified pressures and temperatures in the plant, when divided by the number of installed boilers, will give the _______________.

Aefficiency of each fire room
Boverload capacity for each boiler
Cefficiency of each boiler
Dfull power capacity of each boiler
AI Explanation

The correct answer is D) full power capacity of each boiler. The required number of pounds of steam generated per hour to develop the contract shaft horsepower and maintain the specified pressures and temperatures in the plant, when divided by the number of installed boilers, will give the full power capacity of each boiler. This is because the full power capacity of a boiler is the maximum steam generation capacity it can achieve under optimal conditions. The other options are incorrect because they do not accurately describe what the calculation represents. Efficiency refers to the ratio of useful output to total input, while overload capacity is the temporary maximum capacity beyond the normal full power capacity.
