In the engine of a car that uses petrol as fuel, when the piston is at its highest position, air at 10 bar and 100°C enters the cylinder. Without any change in the volume, ignition occurs, and the air temperature rises to 1500°C. What is the air pressure after the ignition? (Select the closest value)[Whenever necessary, assume air as an ideal gas and consider R = 287 J/(kg.K).]
A rigid, well-insulated tank contains air. A partition in the tank separates 12 ft^3 of air at 14.7 lbf/in2, 40◦F (left side of the tank) from 10 ft^3 of air at 50 lbf/in2, 200◦F(right side of the tank), as illustrated in the figure. The partition is removed and air from the two sides mix until a final equilibrium state is attained. The air can be modeled as an ideal gas, and kinetic and potential energy effects can be neglected. (Note: values for the left side of the tank are denoted with a subscript L, and values for the right side of the tank are denoted with a subscript R). a) Determine the final temperature (in F) b) Determine the final pressure (in lbf/in^2) c) Calculate the amount of entropy produced, in Btu/R d) Is this mixing process reversible or irreversible?
