Question:
A perfect gas of average molecular weight of 28, at a temperature of 1500 degree F and a pressure of 7 atm, is expanded through a special turbine to a pressure of 1 atm. This turbine is so designed that the exhaust gases leaves with substantial velocity. When the gas flow rate is 100 lb per hour, the turbine produces rated output of 3.5 kW. Heat losses from the turbine are estimated to be 6500 BTU/hr. The piping to and from the turbine is 0.622 inches. The heat capacity of the gas, assumed independent of temperature and pressure is 0.24 BTU/lb-degree Fahrenheit.
Required:
What is the velocity of the exit gas in ft/s?
