Question:
A crude but effective approach to estimate steam leak (in lb/hr) from an orifice is to use the following expression:
Estimate the hourly, monthly, and annual costs of steam leaks from a 300-psig pipe. The steam is generated from a gas boiler with an efficiency of 80 percent. The cost of natural gas is $0.90/therm (1 therm is equivalent to 100,000 Btu/hr). The heating season spans seven months per year. Provide the costs for the following orifice diameters: 1/16; 1/8; 1/4; 3/8; 1/2; and 1 in.
