1. Solve no.02 and show clear solutions. Write the GIVEN and REQUIRED. Thanks!!!

NOTE: ANSWER LETTER A ONLY.

2. A turbine operates under steady flow conditions, receiving steam at 1200 kPa,
enthalpy 2785 kJ/kg, velocity of 33 m/s and elevation of 3 m. The steam leaves at
20 kPa, enthalpy of 2512 kJ/kg, velocity of 100 m/s and elevation of 0 m. Heat is
lost to the surroundings at the rate of 1.8 kJÍs. If the steam flow rate through the
turbine is 0.4 kg/s, determine the following:
a. the change in potential energy in kW
0.01176
-11.7684
-0.01176
b. the change in kinetic energy in kW
1,782.2
1.7822
-1.7822
c. the change in enthalpy in kW
-0.1092
-109.2
109.2
d. the work of the turbine in k
105.629
107.729
106.129
