Question
A rigid tank initially contains 2 kg of water at 100 C and 40 percent
quality. The water is stirred by a shaft until the pressure reaches 600
kPa. During this process 500 kJ of heat is lost to the environment. It is
also known that the initial internal energy of the water is 1253.9 kJ/kg and
the initial specific volume of the water is 0.66943 m³/kg.
In the question that follows, select the answer that is closest to the true value.
What is the amount of work done on the water during this process in units
of kJ?
