The gross area of an exhibition facility is 10,000 square feet. What number of individual people is used to calculate facilities?
The distance from a meter to a natural gas water heater (40,000 btuh) is 30 feet, 20 feet further down the line is a furnace (120,000btuh). What is the minimum gas pipe size that must be used between the water heater and furnace? (pressure drop =.05) a. 3/8" b. ½" c. ¾" d.1". It looks like you need to know maths very well and know how to calculate well. Good luck. :-)
