A natural gas contains 95 wt% CH4 and the balance C2H6. Five hundred cubic meters per hour of this gas at 40 ̊C and 1.1 bar is to be burned with 25% excess air. The air flowmeter is calibrated to read the volumetric flow rate at standard temperature and pressure. What should the meter read (in SCMH) when the flow rate is set to the desired value?

220

An open graduated cylinder at 25 °C is filled with mercury and water. The height of mercury is 7.0 cm and the water is 5.6 cm. Calculate the pressure at the bottom of the test tube (kPa) if the atmospheric pressure is 755 mm Hg. (Specific gravity of mercury and water are 13.6 and 1.0 respectively). Report answer in kPa

Nitrogen gas enters a 0.450 m diameter pipe at 30.0 °C, 2.60 atm (absolute), and 6.30 m/s. The pipe rises 24.0 ft and then falls 99.0 ft. The nitrogen gas exits the pipe at 30.0 °C and 1.10 atm (absolute). The ultimate goal is to find AEK and AEp in the process. Assume N₂ behaves ideally. What is V₁, the volumetric flow rate of nitrogen gas into the pipe section? V₁ = 1 What is m, the mass flow rate into the pipe? z, ft T, °C P, atm (absolute) u, m/s z, ft T₂ °C P, atm (absolute) u, m/s m³/s
