A fluid with a specific volume of 0.2m3 /Kg at 500KPa pressure enters a system with 8 m/s velocity. Heat losses in the system are found out to be 50 KJ/Kg of fluid supplied. The leaving pressure of the fluid is 100Kpa with a specific volume of 0.1m3 /Kg with a 10 m/s velocity. If the work done by the fluid equals to 700KJ/Kg, find the change in internal energy of the system.
