While discussing the catalyst efficiency monitor: Technician A says that if the catalytic converter is not reducing emissions properly, the voltage frequency increases on the downstream HO2S. Technician B says that if a fault occurs in the catalyst monitor system on three drive cycles, the MIL will be illuminated. Who is correct?

    5 0/20 points awarded Scored A pressurized tank of water has a 10-cm-diameter orifice at the bottom, where water discharges to the atmosphere. The water level is 2.5 m above the outlet. The tank air pressure above the water level is 250 kPa (absolute), while the atmospheric pressure is 100 kPa. Neglecting frictional effects, determine the initial discharge rate of water from the tank. (Round the final answer to three decimal places.) -Air 250 kPa dcm 2.5 m The initial discharge rate of water from the tank is determined to be 18.683 m³/s.
    10 0/10 points awarded Scored A 3-m-high large tank is initially filled with water. The tank water surface is open to the atmosphere, and a sharp-edged 10-cm-diameter orifice at the bottom drains to the atmosphere through a horizontal 80-m-long pipe. The total irreversible head loss of the system is determined to be 1.500 m. In order to drain the tank faster, a pump is installed near the tank exit. Determine the pump head input necessary to establish an average water speed of 6.5 m/s when the tank is full. Disregard the effect of the kinetic energy correction factors. (Round the final answer to three decimal places.) Water 3 m 10 cm 80 m The required useful pump head is 1.200 m.
    (30 minutes) Consider a converging-diverging nozzle, which is open to stagnant atmosphere at the inlet and connected to an infinitely large low-pressure reservoir downstream at the outlet (see the figure below). The ambient pressure (pa) is 1 bar, the throat cross section area is 0.1 m². Imagine that the pressure in the low-pressure reservoir (p₁) can be changed to regulate the flow in the nozzle. Me Pa=1 bar A₁ =0.1 m² Ae Pv Pe Low pressure reservoir a) It is known that when p₁ = 0.8 bar, the nozzle is choked and the flow in the converging- diverging nozzle is subsonic. Find the exit cross-section area (Ae), the static pressure at the exit (pe) and the Mach number at the exit (Me) for this case. b) Determine the range of vacuum pressure (pv) for which there is a normal shock wave in the diverging section of the nozzle. c) Imagine that a pitot-tube is inserted at the exit of the nozzle. What would be the total pressure reading when: (1) p₁ = 0.8 bar; (2) p, is adjusted such that the…
