Convert 60,000 BTU/hr to in.cubic feet/minute.

To convert BTU/hr (British thermal units per hour) to in.cubic feet/minute (cubic feet per minute), we need to use a conversion factor.

First, let's break down the conversion factor:

1 BTU = 778.169 ft.lbf (foot-pounds)
1 ft.lbf = 1/5,400 horsepower.hour
1 horsepower = 2,545.5 BTU/hr
1 hour = 60 minutes

Now, let's calculate the conversion:

Step 1: Convert BTU/hr to ft.lbf/hr
To do this, we divide 60,000 BTU/hr by the conversion factor of 778.169 ft.lbf/BTU:
60,000 BTU/hr ÷ 778.169 ft.lbf/BTU = 77.14 ft.lbf/hr

Step 2: Convert ft.lbf/hr to ft^3/min
Since we're trying to convert to in.cubic feet/minute, we will need to convert ft.lbf/hr to ft^3/min.

To do this, we divide the ft.lbf/hr value by the conversion factor of 1/5,400 horsepower.hour:
77.14 ft.lbf/hr ÷ (1/5,400 horsepower.hour) = 77.14 ft.lbf/hr ÷ 0.000185185 horsepower = 416,327.19 horsepower

Now, since 1 horsepower is equivalent to 2,545.5 BTU/hr, we need to convert the horsepower to BTU/hr:
416,327.19 horsepower × 2,545.5 BTU/hr = 1,058,868,716.45 BTU/hr

Step 3: Convert BTU/hr to in.cubic feet/minute
Finally, we convert BTU/hr to in.cubic feet/minute by dividing by the conversion factor of 60 minutes:
1,058,868,716.45 BTU/hr ÷ 60 minutes = 17,647,812.94 in.cubic feet/minute

Therefore, 60,000 BTU/hr is equivalent to approximately 17,647,812.94 in.cubic feet/minute.
