How many BTU'S in a steam line if the pressure is 140 PSI?

To calculate the BTUs in a steam line at 140 PSI, you first need to determine the enthalpy of the steam at that pressure. At 140 PSI, the saturation temperature is approximately 366°F, and the enthalpy of saturated steam is about 1,200 BTU per pound. Therefore, if you have the mass flow rate of steam, you can multiply it by the enthalpy to find the total BTUs being carried in the steam line.
