Question 1 of 10

Heating, Ventilation & Air Conditioning Systems

A steam survey finds a trap failed open, passing an estimated 25 lb/h of live steam. The steam system operates 6,000 h/yr, each pound of lost steam represents 1,000 Btu of boiler output, and the gas-fired boiler is 80% efficient. Gas costs $1.20/therm. Calculate the annual cost of the failed trap.
