Gas Fitter Practice Test

Question: 1 / 455

What would be the maximum input in Btu for a 20 horsepower steam boiler?

200 Mbtu

530 Mbtu

680 Mbtu

To determine the maximum input in BTUs for a 20 horsepower steam boiler, it is essential to understand the relationship between horsepower and BTUs. The conversion standard is that 1 horsepower is equivalent to approximately 33,475 BTU/hour. Therefore, to find the maximum input in BTUs for a 20-horsepower boiler, we can multiply the total horsepower by this conversion factor.

Calculating this, we have:

20 horsepower x 33,475 BTU/hour = 669,500 BTU/hour

In the context of the options provided, this calculation approximates to 680 MBtu. This demonstrates how the maximum input is derived from converting horsepower to BTUs and ensures that the selected answer accurately reflects the maximum capacity for that output. Hence, understanding the relationship and calculations involved allows for proper determination of energy requirements in steam boiler systems.
