Assume the space shuttle is in a circular orbit about earth with its nose pointing forward. the rocket motors are fired for a few moments. you would expect the shuttle to speed up. show that, instead, it actually rises to a higher orbit and slows down. (this behavior is called the "satellite paradox.")

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
