A stoichiometric mixture of hydrogen and air is compressed to 18.63 bar and 845 °C. It burns adiabatically at constant volume. Show that the final equilibrium temperature is 3300 K and the degree of dissociation is 8.85%. Calculate the final pressure after combustion. Show the process, including the effect of dissociation, on a U-T diagram. The equilibrium constant is
Use the following internal energies
The light bracket ABC is freely hinged at A and is constrained by the fixed pin in the smooth slot at B. Calculate the magnitude R of the force supported by the pin at A under the action of the 80- N · m applied couple
a rigid container with a volume of 0.17m3 is initially filled with steam at 180kpa 340c. it is colled to 90c. a at what
A wind turbine with a diameter of 100 ft operates during a 24-h period in which the wind velocity may be approximated by half a sine wave as V(theta)=V(m)sin(pi*theta/24), where theta is time in hours and V(m)= 10^5 ft/h. The wind density is 0.076 l..
Air at 500 kPa, 500 K and a mass flow of 600 kg/h enters a pipe passing overhead in a factory space. At the pipe exit, the pressure and temperature of the air are 475 kPa and 450 K, respectively. Air can be modeled as an ideal gas with k 5 1.39. K..
A Rigid, 85-L steam cooker is arranged with a pressure relief valve set to release vapor and maintain the pressure once the pressure inside the cooker reaches 200 kPa. Initially, this cooker is filled with water at 200 kPa with a quality of 8 percent..
