Water vapor at 8 mpa and 520°c enters a well-insulated turbine at steady state with a mass flowrate of 4 kg/s and exits at 1 bar and a quality of 95%. kinetic and potential energy effects are negligible. determine the (a) power developed by the turbine, in kw (b) rate of entropy production, in kwik (c) isentropic turbine efficiency

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

An electron in an x-ray machine is accelerated through a potential difference of 1.00 × 104 v before it hits the target. what is the kinetic energy of the electron in electron volts?
