The power out of an adiabatic steam turbine is 5 MW and the steam enters turbine at 2 MPa and velocity of
50 m/s, specific enthalpy (h) of 3248 kJ/kg. The elevation of the inlet is 10 m higher than at the datum. The
vapor mixture exits at 15 kPa and a velocity of 180 m/s, specific enthalpy (h) of 2361.01 kJ/kg. The elevation
of the exit is 6 m higher than at the datum. Let g = 9.81 m/s². Assuming the ideal gas model and R = 0.462
KJ/(kg.K). The steam specific heat ratio is 1.283. Calculate:

SOLVE BY HAND STEP BY STEP A solution containing 7.5% sulfuric acid by weight at 70 °F is concentrated to 45% by weight by evaporating water. The concentrated solution and the water vapor exit the evaporator at 170 °F and 1 atm. Calculate the rate at which heat must be transferred to the evaporator to process 1500 lbm/hr of the feed solution to the evaporator. It is recommended to use the enthalpy-concentration diagram for sulfuric acid from Chapter 8 of Felder's book or an enthalpy-concentration diagram for sulfuric acid found in another unit operations book or chemical engineering manual such as Perry's.arrow_forwardPLEASE SOLVE STEP BY STEP WITHOUT ARTIFICIAL INTELLIGENCE OR CHATGPT I don't understand why you use chatgpt, if I wanted to I would do it myself, I need to learn from you, not from being a d amn robot.
