A88.9 kg tight rope walker falls from a wire positioned above a safety net. if their potential energy exactly half way down from the top is 2,338 j, what height was the wire positioned above the safety net? note : therefore, if using accelration due to gravity, only use positive 9.81 m/s/s , express your answer as a number rounded to 2 decimal places

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.
