3. (10 pts) Fill in all blanks in the following table on the basis of conservation of energy principle for a closed system. point per item.) Wout (kJ) Qin (kJ) Einitial (kJ)Efinal (kJ) m (kg)efinal-Cini efinal-einitial J/k 2040 1100 1200 1400 1000 700 1720 10 4 10 260 700 520 300 -500 900 -50 200

Solution

Energry Conservation Follows like this

E_final -E_initial = Q_in - W_out

1. 1720-2040 =700-W_out   ;W_out =1020 kJ     ; e_final - e_initial =(1720-2040)/5 =-64 kJ/kg

2. E_final- 1100 =700-260 ; E_final = 1540 kJ ;    e_final - e_initial =(1540 - 1100)/10 =44 kJ/kg

3. E_final - 1200 = Q_in -520;                             (E_final - E_initial )/4 = 300

      2400-1200 =Q_in -520                                                      E_final = 1200 +1200 =2400 kJ

Qin = 1720 kJ                       

4. 900-1400= 500 -W_out;W_out = 1000kJ ;e_final-e_initial =( 900-1400)/10=-50 kJ/kg

5. E_final - 1000 = Q_in +50; ( E_final - 1000)/3 =-200 ; E_final =400 kJ

400 -1000 = Q_in +50 ;; Qin =-650 kJ
