A boiler with 3450 square feet of heating surface designed for 5 square feet of heating surface per BHP has how many horsepower?

A boiler with 3450 square feet of heating surface designed for 5 square feet of heating surface per BHP has how many horsepower?

• A. 345
• B. 690
• C. 1000
• D. 1725

Answer: (B)

To determine the horsepower (BHP) of a boiler based on its heating surface area and the design specification of heating surface per BHP, you can use the formula: \[ \text{Horsepower (BHP)} = \frac{\text{Total heating surface area (sq. ft.)}}{\text{Heating surface per BHP (sq. ft.)}} \] In this scenario, the boiler has 3450 square feet of heating surface, and it is designed for 5 square feet of heating surface per BHP. Plugging these values into the formula gives: \[ \text{BHP} = \frac{3450 \text{ sq. ft.}}{5 \text{ sq. ft./BHP}} = 690 \text{ BHP} \] This calculation shows that the boiler can deliver 690 horsepower, which aligns perfectly with the design parameter of the heating surface area per horsepower. Understanding this relationship allows engineers to evaluate their boiler systems effectively, ensuring they meet required performance standards for various applications.

To determine the horsepower (BHP) of a boiler based on its heating surface area and the design specification of heating surface per BHP, you can use the formula:

[ \text{Horsepower (BHP)} = \frac{\text{Total heating surface area (sq. ft.)}}{\text{Heating surface per BHP (sq. ft.)}} ]

In this scenario, the boiler has 3450 square feet of heating surface, and it is designed for 5 square feet of heating surface per BHP. Plugging these values into the formula gives:

[ \text{BHP} = \frac{3450 \text{ sq. ft.}}{5 \text{ sq. ft./BHP}} = 690 \text{ BHP} ]

This calculation shows that the boiler can deliver 690 horsepower, which aligns perfectly with the design parameter of the heating surface area per horsepower. Understanding this relationship allows engineers to evaluate their boiler systems effectively, ensuring they meet required performance standards for various applications.
