Technician A says that HID headlamps frequently fail because they are more vulnerable to road shock and vibration than halogen filament lamps. Technician B says that when HID headlamps fail, it is usually due to frequent cycling. Who is correct

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
