Air (diatomic, MW = 28.8664 g/ mol) in an automobile tire is maintained at a pressure of 220 ka (gage) in an
environment where the atmospheric pressure is 94 kPa. The air in the tire is at the ambient temperature of 25°C.
A 4-mm-diameter hole develops in the tire as a result of physical damage. Approximating the gas flow as isentropic, determine the initial mass flow rate (kg/min) of air through the leak. Check first for choking.
In the boiler design, it is desirable to have the flue gas exit temperature above the dew point. Estimate the partial pressure of water vapor of the flue gas in kPa produced by combustion having the gravimetric analysis of:
N2=71.84%, CO2=20.35% , O2=3.61%, H2O=4.20%
A single-effect evaporator concentrates 4.00 kg/s of a 10% by mass solution of H2SO4. The entering feed is at 25 °C. The vapor released at the top has a mass flow rate of 3.20 kg/s. The evaporator operates at a total pressure of 30.2 kPa at 90 °C. What is the rate of heat transfer in the evaporator? Use a steam table for the enthalpy of the vapor?
