Bob is asked to design a system for heating process water in a chemical plant. The system is to heat 500 gallons of water from room temperature 70 degrees F to 200 degrees F every hour. Assume that the system is 90% efficient in changing chemical energy in the fuel into internal energy of the water.
A). What capacity of natural gas burners must Bob provide, measured in BTU/H?
B). How much natural gas will Bob consume(lbs/hr)?
