A certain gas was produced as a product of a decomposition reaction in a reactor vessel. The reaction generated a certain amount of force that allowed the gas to move at 35 m/s. The diatomic product gas (gamma = 1.36) will be transported adiabatically in a commercial steel pipe with a diameter of 1 inch. If the exit of the reactor and start of the pipe has a same pressure of 6 atm abs. and temperature of 120 degrees Celsius. The molecular weight of the gas is 70.91 kg/kgmol. 2. What is the Mach No. at the entry of the pipe? 0.36 0.41 0.14 none of the given

Compare the predicted ro for the two mass fraction cases. Provide a plausible reason for why the boiling heat transfer coefficient for a given AT's for…

The aluminum fuel tank (α = 23.8 x 10-6 m/moC) on a sailboat measures 40 cm by 50 cm by 75 cm. If it is filled with 10oC gasoline from an underground tank, how much fuel will leak out when the fuel and the tank return to 28oC ambient temperature?

In a paint manufacturing process, two different colored paints are being mixed in an infinitelylarge drum.Paint A, with a concentration of 30% pigment, is pumped into the drum at a rate of 10 liters perminute.Paint B, with a concentration of 17% pigment, is pumped into the drum at a rate of 17 liters perminute.Both paints have the same density of 1.0 kg/liter.If the mixture is cotinuously stirred and drained from the drum at a rate of 22 liters perminute, what isthe concentration of pigment in the resulting mixture?

Imagine that you have a rigid leak-proof container that contains nitrogen (N2) gas at atmospheric pressure and room temperature (25 °C). Now imagine that a small quantity of liquid water is added to the chamber without letting in any outside air. After some time, the air in the container is tested and is found to contain not only nitrogen gas but water vapor as well – even though the temperature never rose above 25 °C – and that the total pressure in the container increased to 1.30 atmospheres. Assuming all gasses are acting like ideal gasses, (i) calculate the final pressure of nitrogen and water vapor in the container and (ii) state what these individual pressures are called.
