![4. An amount of heat equal to 2500 J is added to a system, and 1800 J of work is done
on the system. What is the change in internal energy of the system? (:
5. Determine the change in internal energy of 1.0L of water at 100 deg C when it is fully
boiled, which results in 1671 L of steam at 100 deg C. Assume the process is done at
atmospheric pressure. : ta)
6. A steady flow machine produces 405 kW of work with the following conditions: (
m = 3 kg/s
V1 =0.37 m/kg
P1 = 6 bar
v1 = 16 m/s
V2 =0.62 m/kg
P2 = 1 bar
v2 = 270 m/s
z2 = 0m
Q out = 9 kJ/kg
