What would be the input of a 0.60-gph-oil nozzle?

The input of a 0.60 gallons per hour (gph) oil nozzle can be calculated using the formula that relates the flow rate of the fuel (in gph) to the thermal input in British thermal units (Btu). When working with oil burners, it's common to use the multiplier of 140,000 Btu per gph to determine the input based on the nozzle size.

In this case, the calculation looks like this: 140,000 Btu/gph multiplied by the flow rate of the nozzle, which is 0.60 gph. So, 140,000 multiplied by 0.60 gives you 84,000 Btu.

The correct answer, therefore, is that the input for a 0.60-gph oil nozzle is 84 MBtu. This figure reflects how much heat energy can be produced by the burner using that specific flow rate of fuel. This understanding is crucial for ensuring proper sizing of heating equipment and optimizing efficiency in heating applications.
